The Hidden Battery Metal Powering the Next Generation of Electric Vehicles

The Hidden Battery Metal Powering the Next Generation of Electric Vehicles

Lithium gets the headlines. Cobalt gets the controversy. Nickel attracts attention whenever automakers promise longer driving range.

But another metal sits quietly inside the electric vehicle battery story: manganese.

Manganese is not new. It has been used in steelmaking for generations, and it already appears in several common lithium-ion battery chemistries. What is changing is the role it could play in the next wave of batteries designed to be more affordable, safer and less dependent on cobalt and nickel.

The opportunity is easy to misunderstand. The world is not running out of manganese ore. Manganese is mined in several countries, and more than 90% of global manganese consumption still goes into steel production. Battery materials account for only a small share of the total market today.

The more important question is whether the battery industry can produce enough manganese at the purity, consistency and location required by cathode manufacturers.

An electric vehicle battery cannot simply use ordinary manganese ore taken from the ground. Battery makers require specially processed material, often in the form of high-purity manganese sulphate monohydrate. Small levels of unwanted metals can affect battery performance, consistency and lifespan.

That creates an unusual supply-chain problem.

The raw mineral may be widely available, but the ability to refine it into a qualified battery product is highly concentrated. The International Energy Agency estimates that China currently accounts for approximately 95% of global battery-grade manganese sulphate production. It also warns that announced projects could cover only 55% of expected demand in 2035 under its Stated Policies Scenario. (IEA)

This does not guarantee a shortage. Battery technologies can change, projects can be delayed and new capacity can appear faster than expected. Still, it reveals why manganese deserves more attention.

The hidden battle may not be over who owns the largest mine.

It may be over who can turn ordinary material into battery-grade chemicals, qualify that product with manufacturers and deliver it reliably to factories for years.

Why the EV Industry Is Searching Beyond Cobalt

Cobalt has played an important role in lithium-ion batteries because it helps improve stability and performance. It is commonly used alongside nickel and manganese in nickel-manganese-cobalt, or NMC, cathodes.

However, cobalt also brings several challenges.

Its supply chain is geographically concentrated. Prices can be volatile. Mining conditions have raised social and ethical concerns. Automakers and battery companies have therefore spent years reducing the amount of cobalt used in each battery pack or removing it from some designs entirely.

This shift does not mean cobalt is disappearing. High-performance applications may continue using cobalt-containing chemistries where energy density, charging performance and range justify the cost.

But the market is becoming more diverse.

Lithium iron phosphate batteries, commonly called LFP batteries, contain no nickel or cobalt. They have gained market share because they can offer lower costs, strong cycle life and good thermal stability. Their main disadvantage is lower energy density compared with some nickel-rich batteries, which can affect vehicle range or pack weight.

That trade-off has encouraged interest in lithium manganese iron phosphate, or LMFP.

LMFP builds on the basic structure of LFP but adds manganese. The goal is to increase operating voltage and energy density while preserving many of the safety and cost advantages associated with phosphate-based batteries.

Research and government-supported development programmes continue to explore LMFP as a potential step forward from conventional LFP. A United States Department of Energy-backed project, for example, has targeted more than a 20% improvement in cell-level energy density compared with LFP while aiming for a cycle life of more than 1,000 cycles. Those are development goals rather than guaranteed commercial results, but they show why the chemistry is receiving attention. (The Department of Energy's Energy.gov)

Manganese is also relevant beyond LMFP. It is already used in many NMC batteries, and researchers are developing other manganese-rich cathodes that could reduce reliance on more expensive materials.

The larger trend is clear: battery manufacturers are no longer betting on one chemistry for every vehicle.

Premium electric cars may use one battery design. Affordable city vehicles may use another. Trucks, stationary storage systems, hybrids and entry-level cars may each require different balances of cost, range, weight, safety and durability.

Manganese can participate in several of these pathways, which is one reason its battery-grade supply chain matters.

Manganese Is Common, but Battery-Grade Manganese Is Not

Calling manganese a “rare” battery metal would be misleading.

The metal is produced at scale and has a large established industrial market. South Africa, Gabon, Australia and other countries hold important ore resources and mining operations. Most of this material serves the steel industry, where manganese improves strength, hardness and resistance to wear.

Battery production is different.

A steel producer and a battery cathode manufacturer are not buying the same product. A battery company may require manganese sulphate with extremely low concentrations of iron, sodium, calcium, magnesium, heavy metals and other impurities.

The challenge is not only reaching a high headline purity percentage. The chemical composition must remain consistent from one shipment to the next.

Battery factories operate under tightly controlled conditions. Their production lines are designed around exact material specifications. An impurity that appears insignificant in a conventional industrial application may interfere with cathode performance or manufacturing yield.

This is why the term “high-purity manganese” can cover several forms depending on the battery chemistry and production route. These include high-purity manganese sulphate, electrolytic manganese dioxide and electrolytic manganese metal. The sulphate form is particularly important because it can serve as a precursor for several cathode materials. (U.S. Geological Survey)

The difference between ore and battery-grade product explains why a large resource does not automatically become a valuable battery supply business.

A project must prove that it can:

extract manganese economically;

remove unwanted elements;

produce a repeatable chemical product;

meet environmental requirements;

operate at commercial scale;

and pass a customer’s qualification process.

Each step introduces risk.

A laboratory can produce a small quantity of pure material. A pilot plant can demonstrate a larger process. A demonstration facility can generate samples for potential customers.

But none of these stages guarantees that a full commercial refinery will operate smoothly for decades.

That gap between geological potential and qualified production is where much of the manganese story will be decided.

The Refining Process Is the Real Technical Barrier

The idea of turning low-grade ore into a valuable battery chemical sounds simple. In practice, it requires a carefully designed chain of chemical reactions and separation stages.

One point needs clarification: high-pressure acid leaching, or HPAL, is often discussed in relation to battery metals, but it should not be treated as the universal process for producing battery-grade manganese.

HPAL is strongly associated with processing certain nickel and cobalt laterite ores. Some manganese projects may use pressure, heat or specialised leaching technologies, but high-purity manganese production can follow several different hydrometallurgical routes.

A typical process begins by preparing the manganese-bearing material. The feed may come from freshly mined ore, a concentrate, old mine tailings or industrial waste.

The material is crushed or ground to increase the surface area available for chemical treatment. It may also require roasting or another pre-treatment step, depending on the mineral form and the impurities present.

Next comes leaching.

An acidic solution, often involving sulphuric acid, dissolves manganese from the solid material. A reducing agent may be added because certain manganese oxides do not dissolve efficiently under ordinary conditions.

The result is not yet a clean battery product. It is a liquid containing dissolved manganese along with unwanted elements.

The difficult stage is purification.

Operators may adjust the acidity of the solution, add reagents that cause selected impurities to precipitate, use filtration, apply solvent extraction, perform ion exchange or repeat several purification stages. Iron, aluminium, calcium, magnesium, zinc, copper, nickel, cobalt and heavy metals may each require different treatment.

Once the solution meets the required specifications, the manganese can be crystallised as manganese sulphate monohydrate. Drying, packaging and contamination control are also important because the final product must remain within specification during transport and storage.

Published research has demonstrated routes that recover manganese from low-grade materials and industrial residues using combinations of acid leaching, impurity precipitation and crystallisation. The exact process is not one-size-fits-all; it must be designed around the chemistry of the feed material. (Taylor & Francis Online)

This is the real “chemical alchemy” of the manganese industry.

The value does not come from making manganese appear from nothing. It comes from separating it from everything a battery manufacturer does not want.

Why China Holds Such a Powerful Position

China’s dominance in battery materials did not appear overnight.

It developed through years of investment in mining partnerships, chemical processing, industrial equipment, skilled labour, cathode production and battery manufacturing. These activities reinforce one another.

A refinery located near chemical suppliers, cathode manufacturers and cell factories can operate inside an integrated industrial network. By-products may have nearby buyers. Technical problems can be solved by experienced equipment companies. Customers can test and qualify materials without sending samples across the world.

This creates advantages that are difficult to reproduce by building one isolated plant.

The manganese market illustrates the power of the midstream.

Mining is the upstream stage. Battery cells and electric vehicles sit further downstream. Between them is a less visible network of refiners, chemical producers, precursor manufacturers and cathode plants.

The International Energy Agency estimates that China produces about 95% of the world’s battery-grade manganese sulphate. It also holds a strong position in LFP cathode materials and LFP battery-cell manufacturing. (IEA)

That concentration does not mean every non-Chinese manufacturer must stop using manganese. International trade can continue, and China has supplied enormous quantities of battery materials to the global market.

The concern is resilience.

Automakers do not want production to stop because of export restrictions, port disruptions, political tensions, shipping delays or an accident at a small number of facilities.

A company may accept a slightly higher cost for a second source if that source lowers the risk of shutting down an entire vehicle factory.

This is why North America, Europe, Africa and Australia are exploring new manganese refining capacity. The objective is not necessarily to eliminate Chinese supply. That would be extremely difficult and may not be economically sensible.

The more realistic goal is diversification.

A supply chain with several qualified producers in different regions can respond more effectively to disruptions than one dependent on a single processing centre.

The New Global Manganese Supply Web

The emerging manganese supply network is not one project or one country. It is a collection of mines, tailings-recovery operations, demonstration facilities and planned refineries at different stages of development.

Some are close to ore deposits. Others are being positioned near battery factories and automotive customers.

Africa: Moving Beyond Raw-Material Exports

Africa already plays a major role in global manganese mining, but much of the value has historically been captured after raw materials leave the continent.

Battery-grade processing could change that model.

Botswana’s K.Hill project is designed around the production of high-purity manganese sulphate rather than only shipping conventional manganese ore. Botswana granted the project a mining licence in 2024, and its developer has been working through demonstration and feasibility stages. (Reuters)

The project is important for more than its potential production volume.

It represents an attempt to connect African mineral resources with a higher-value battery chemical. Success could create local technical skills, processing employment and industrial capabilities. Failure or delay would also demonstrate how difficult it is to finance and scale a new critical-minerals project.

Large resource estimates and positive feasibility studies should therefore be treated as milestones, not as proof of future commercial supply.

Europe: Turning Legacy Waste Into Strategic Material

Europe has limited domestic access to many battery materials, which makes recycling, tailings recovery and local processing strategically important.

The Chvaletice project in the Czech Republic plans to recover manganese from historical mine tailings rather than develop a conventional new mine. The European Commission included Chvaletice among the strategic projects selected under the Critical Raw Materials Act in 2025. (Internal Market & SMEs)

The concept has two attractions.

First, the project could produce a battery material inside the European Union. Second, reprocessing old waste could address an existing environmental liability while recovering useful minerals.

However, strategic status does not remove every obstacle. Projects still face permitting, infrastructure, financing and construction challenges. Recent reporting has highlighted delays affecting European critical-minerals developments, including Chvaletice. (Reuters)

The lesson is important: government recognition can improve a project’s position, but it cannot automatically deliver a working refinery.

Australia: Moving From Mining to Cathode Materials

Australia is a major mining country, but it has often exported raw or partially processed materials before the highest-value manufacturing stages occur elsewhere.

New manganese initiatives are trying to move further down the value chain.

In 2026, the Australian Renewable Energy Agency announced support for a demonstration-scale facility in Perth led by Firebird Metals. The project is intended to process manganese concentrate into high-purity manganese sulphate and other manganese-based battery materials, including cathode active material. (Australian Renewable Energy Agency)

The facility is significant because it aims to test an integrated concentrate-to-cathode pathway under Australian operating and environmental conditions.

Again, the word “demonstration” matters.

The plant is designed to validate technology, produce samples and reduce commercial risk. It is not yet proof that Australia will become a large battery-grade manganese supplier.

North America: Refining Close to Automakers

North America’s strategy increasingly focuses on placing battery-material processing close to cathode factories, cell plants and vehicle assembly operations.

A refinery near customers can reduce shipping time, simplify qualification and provide manufacturers with a regional source of material.

Element 25 has been developing plans for a high-purity manganese sulphate facility in Louisiana linked with automotive customers. However, in May 2026 the company said it was reviewing its execution plan and seeking changes to arrangements as EV demand conditions evolved. (Reuters)

That development captures the reality of the sector.

A project can be strategically attractive and still face commercial uncertainty. Changes in EV sales, battery chemistry, construction costs, government support or customer requirements can reshape a refinery before it reaches production.

Asia: The Existing Centre of Gravity

While new projects are appearing elsewhere, Asia—especially China—remains the centre of the global battery supply chain.

It combines chemical refining with cathode manufacturing, battery equipment, cell production and the world’s largest electric vehicle market.

New Western facilities must compete not only with Chinese product prices, but with an entire integrated system.

This means diversification will probably take time. It may also require long-term customer agreements, public financing, tax support and policies that reward regional production.

Why Refiners May Hold More Leverage Than Miners

Mining companies traditionally attract attention because they control deposits. In battery materials, that is only one part of the value chain.

A refinery can create leverage by becoming one of a limited number of qualified suppliers.

Qualification is a major barrier.

A battery manufacturer cannot casually switch chemical suppliers whenever a cheaper offer appears. It may need months or years of testing to confirm that a new material performs consistently. The supplier must demonstrate product quality, manufacturing controls, traceability and reliable deliveries.

Once approved, the relationship can become valuable to both sides.

The manufacturer gains supply security. The refiner gains a customer that may be reluctant to change suppliers without a strong reason.

This does not mean refining is automatically more profitable than mining. Chemical plants are expensive to construct and operate. They consume energy, water and reagents. They must manage waste safely. A small technical failure can reduce recovery rates or push impurities above acceptable limits.

Refiners can also be trapped between volatile ore prices and customers demanding lower chemical prices.

The strongest operators may therefore be those that control several parts of the chain.

An integrated business might own or secure feedstock, operate a refinery, produce cathode precursors and hold long-term supply agreements with battery customers.

But integration also increases capital requirements and execution risk.

For readers analysing the industry, announced production capacity should never be viewed in isolation. A more useful set of questions includes:

Has the process operated beyond the laboratory?

Has the company produced material that meets customer specifications?

Has an independent customer qualified the product?

Is feedstock secured?

Are permits and utilities available?

Is financing committed?

Is the proposed price competitive without permanent subsidies?

Those questions separate an interesting resource story from a credible industrial operation.

Why Location Is Becoming a Competitive Advantage

In traditional mining, the quality and size of the deposit can dominate the investment case.

In battery materials, location can be almost as important.

High-purity manganese sulphate may represent a small portion of a battery pack’s total cost, but a missing shipment can interrupt cathode production. That makes dependable logistics valuable.

A refinery positioned near a cluster of cathode plants and gigafactories can offer several advantages.

Transport distances are shorter. Customers can hold smaller inventories. Engineers can respond quickly when quality issues appear. Samples can move between facilities without long international shipping times.

Regional production may also help batteries meet local-content or supply-chain requirements connected with government incentives.

At the same time, proximity to customers cannot compensate for a weak process.

A perfectly located facility that produces inconsistent material will not survive. Nor will a regional plant automatically beat a lower-cost overseas competitor.

The winning location must balance several factors: access to feedstock, clean and affordable electricity, water, chemical reagents, waste-management infrastructure, skilled workers, transportation and customers.

This is why some future manganese projects may not be built next to mines.

Concentrate can be transported to a chemical hub where the refinery has better access to power, ports, reagents and battery manufacturers.

The most valuable asset may not be the mountain containing the metal.

It may be the industrial site where geology, chemistry, logistics and customer demand meet.

Can Low-Carbon Manganese Earn a Green Premium?

Battery companies and automakers are under growing pressure to measure the environmental impact of their supply chains.

That includes emissions from mining, chemical processing and transportation, as well as water consumption, waste management and labour standards.

A manganese producer using renewable electricity, efficient processing and transparent sourcing may offer a lower-carbon product than a supplier dependent on carbon-intensive power or long shipping routes.

The open question is whether customers will pay more for it.

A “green premium” sounds attractive, but automotive manufacturing is highly cost-sensitive. A vehicle company may value lower emissions while simultaneously demanding cheaper materials.

Premium pricing is most likely when low-carbon production helps a customer meet a regulatory requirement, qualify for an incentive, satisfy a corporate emissions target or reduce a serious reputational risk.

In other situations, environmental performance may become a basic condition for market access rather than a reason to pay more.

Companies should therefore be cautious about building an entire business model around an assumed premium.

The more durable advantage may come from combining environmental performance with low operating costs.

A process that uses less energy, fewer reagents and less water can reduce emissions while also lowering expenses. Recovering manganese from mine waste or industrial residues may reduce the need for new extraction, although the environmental benefit depends on the full process and should be measured rather than assumed.

Low-carbon claims will also require credible data.

Customers may demand lifecycle assessments, traceability, third-party audits and detailed information about electricity sources. Marketing language alone will not be enough.

What Could Weaken the Manganese Growth Story?

Manganese has a credible role in the future battery industry, but no battery-material thesis is free from risk.

The first risk is chemistry.

LMFP and other manganese-rich batteries must prove that they can deliver the expected combination of cost, energy density, cycle life and manufacturing reliability at scale.

A material can perform well in research and still struggle during mass production. Problems such as lower conductivity, manganese dissolution or performance degradation may require coatings, additives and process improvements.

The second risk is competition from conventional LFP.

LFP already benefits from large production volumes, mature factories and falling costs. LMFP must offer enough additional performance to justify changes in manufacturing.

The third risk is sodium-ion technology.

Sodium-ion batteries avoid lithium, but they do not remove the manganese opportunity completely. Some sodium-ion cathodes use manganese. Others rely on different materials. The effect on manganese demand will depend on which sodium-ion designs gain market share.

The fourth risk is solid-state batteries.

Solid-state technology could change battery architecture, but it does not automatically eliminate manganese. A solid electrolyte replaces the liquid or gel electrolyte; the battery still requires cathode material. Some future solid-state cells may use manganese-containing cathodes, while others may not.

The International Energy Agency expects solid-state batteries to remain concentrated in premium markets during their early commercial period and indicates that broad mass-market impact will take time. (IEA)

The fifth risk is recycling.

Over the long term, recycling can return manganese and other materials to the battery supply chain. In the near term, however, most electric vehicle batteries produced during the recent growth period are still in use. The IEA notes a substantial time lag before large volumes of end-of-life batteries become available, meaning recycling cannot immediately replace new material supply. (IEA)

Finally, there is execution risk.

A projected supply deficit can encourage too many projects at once. If new refineries reach production before demand develops, the market could temporarily face oversupply and weak prices.

The existence of long-term demand does not guarantee attractive economics for every producer.

The Demand Outlook: Large Growth, Uneven Timing

The broader EV battery market continues to expand.

According to the IEA, global EV battery deployment reached approximately 1.2 terawatt-hours in 2025, almost 30% higher than in 2024. Under its current and stated-policy scenarios, deployment is expected to approach 3 terawatt-hours by 2030 and reach roughly 4 to 5 terawatt-hours by 2035. (IEA)

That growth creates a larger addressable market for cathode materials.

However, manganese demand will not rise in a straight line.

It will depend on the mix of NMC, LFP, LMFP, sodium-ion and other chemistries used across different vehicle segments. A rapid expansion of LMFP would support more battery-grade manganese demand. Continued dominance of ordinary LFP in affordable vehicles could slow that increase.

Automaker decisions will matter enormously.

Once a manufacturer selects a chemistry for a major vehicle platform, it may purchase materials for years. But those decisions are influenced by battery prices, government policy, charging infrastructure, customer preferences and technology performance.

This makes forecasting difficult.

The IEA’s warning that announced battery-grade manganese sulphate projects may meet only 55% of expected 2035 demand is not a promise that prices will rise. It is a signal that the present project pipeline may be insufficient under a particular demand and policy scenario. (IEA)

New projects can still be announced. Existing plants can expand. Demand can disappoint. Battery makers can reduce material intensity or choose different chemistries.

The useful conclusion is not that a shortage is guaranteed.

It is that the supply chain appears unusually concentrated and may require significant investment to keep pace with potential demand.

What to Watch Through the End of the Decade

The manganese story will become clearer through a series of practical milestones.

The first is customer qualification.

Producing a pure laboratory sample is encouraging. Producing repeatable tonnes of material that a cathode manufacturer accepts is far more meaningful.

The second is financing.

Many critical-minerals projects publish ambitious production targets before securing the money required for construction. Investors, lenders and governments will decide which proposals become real facilities.

The third is construction progress.

Costs for labour, equipment and energy can change between a feasibility study and final completion. Delays can weaken a project even when the long-term market remains attractive.

The fourth is commercial adoption of LMFP and other manganese-rich chemistries.

Announcements matter, but actual production volumes matter more. Vehicle launches, cell-factory output and cathode orders will reveal whether these technologies are moving beyond limited applications.

The fifth is policy.

North American and European supply-chain rules can improve demand for regional products, but policy support may change after elections or budget negotiations.

The sixth is environmental performance.

Projects that cannot manage water, waste and emissions responsibly may face local opposition, permitting delays or higher operating costs.

The final milestone is price discipline.

A healthy industry needs prices high enough to support reliable production but not so high that battery companies replace manganese-rich chemistries with alternatives.

The strongest supply chain will not necessarily be the one with the highest short-term price.

It will be the one that can deliver consistent material at a cost automakers can absorb.

The Real Hidden Opportunity

Manganese is unlikely to replace lithium. Lithium remains the central charge-carrying element in conventional lithium-ion batteries.

It is also unlikely to eliminate every use of cobalt or nickel. Different vehicles require different battery characteristics, and no single chemistry is likely to dominate every market.

The more realistic story is subtler.

As the battery industry grows, manganese could become increasingly important across a wider range of chemistries. That creates demand not simply for more ore, but for more high-purity material that meets the exact requirements of cathode manufacturers.

This is where industrial leverage can develop.

A mine creates access to the resource. A refinery converts that resource into a usable chemical. A qualified supplier connects the chemical to a battery factory. A regional network reduces the risk that one disruption stops production.

Each stage matters.

But the least visible stage—the chemical processing between the mine and the cathode plant—may be the hardest to replace.

That is why high-purity manganese deserves attention.

It is not a magical metal that has already solved the electric vehicle battery crisis. It is not a guaranteed investment winner, and a projected supply gap does not ensure that every planned project will succeed.

It is an overlooked part of a much larger industrial transformation.

The future of electric vehicles will not be determined by one dramatic battery breakthrough. It will be shaped by hundreds of improvements in chemistry, manufacturing, energy use, logistics and material supply.

Manganese sits at the intersection of those changes.

The metal itself may be common.

The ability to purify it, qualify it and deliver it at scale is not.

And in the next generation of electric vehicle batteries, that difference could become extremely important.
