What Country Makes the Most Batteries?

Battery factories are expanding worldwide, but global production remains highly concentrated in one country across cells, cathodes, anodes, and finished battery supply chains.

China makes the most batteries in the world. In 2025, China accounted for more than 80% of global battery-cell production, while Chinese battery manufacturers supplied almost 75% of batteries deployed in electric cars worldwide. China also dominates important battery-material stages, giving it a much larger battery manufacturing ecosystem than any other country.

I consider China the clear battery-manufacturing leader whether I look at lithium-ion cell production, manufacturing capacity, battery materials, or major producers. South Korea, Japan, the United States, and European countries remain important, but none currently approaches China's overall scale.

Why Does China Make the Most Batteries?

China's leadership did not come from battery-cell factories alone. The country developed an integrated supply chain covering processed minerals, active materials, battery cells, electric vehicles, and stationary energy storage systems.

China makes the most batteries because it combines enormous domestic demand, large-scale manufacturing, highly developed component supply chains, experienced battery companies, relatively low production costs, and extensive investment in electric vehicles and energy storage. In 2025, China produced more than 80% of global battery cells and held even larger shares of several upstream battery-material stages.

China Produces More Than 80% of Battery Cells

The International Energy Agency reported that China accounted for more than 80% of global battery-cell production in 2025.

That is the clearest answer when I interpret "makes the most batteries" as the physical production location of lithium-ion battery cells.

Battery supply-chain measure	China's position
Global battery-cell production in 2025	More than 80%
Lithium-ion battery supply-chain production capacity	Around 80%
EV battery deployment from Chinese producers in 2025	Almost 75%
Cathode active-material production for EV batteries	About 85%
Anode active-material production for EV batteries	More than 90%

The IEA's 2026 manufacturing analysis places China's share of lithium-ion battery supply-chain production capacity at around 80%. It also reports that China produced about 85% of cathode active material and more than 90% of anode active material used in electric-car batteries during 2025.

This vertical integration is important. A country can assemble battery packs while still importing most of its cells or active materials. China has major capacity across several stages.

Chinese Battery Companies Are Also Global Leaders

Location and company ownership are different measures.

A battery made in a U.S. factory could come from a Korean-headquartered company. A Chinese-headquartered manufacturer can also operate factories outside China.

Even under the manufacturer-ownership measure, China leads.

The IEA reported that Chinese producers supplied almost 75% of batteries deployed in electric cars globally during 2025. Chinese companies also increased their share of the European market, accounting for more than half of EV battery deployment there during the year.

Major Chinese battery manufacturers include:

• CATL
• BYD
• CALB
• EVE Energy
• Gotion High-Tech
• Sunwoda

These companies supply batteries for electric vehicles, stationary BESS projects, commercial storage, residential batteries, and other applications.

China's Domestic Market Creates Enormous Scale

China is also the world's largest electric-car market.

More than 13 million electric cars were sold in China in 2025, representing roughly six out of every ten electric cars sold globally.

A large domestic market allows battery manufacturers to run factories at high utilization, improve production processes, develop local suppliers, and spread fixed manufacturing costs across very large output volumes.

China also led global battery-storage deployment in 2025, accounting for around 60% of worldwide additions.

This creates demand from two enormous sectors:

1. Electric vehicles
2. Stationary energy storage

I see this combination as a major structural advantage for Chinese battery manufacturers.

Which Countries Make the Most Batteries After China?

China has a large lead, but battery manufacturing is expanding in several other regions.

After China, the most important battery-manufacturing centers include South Korea, Japan, the United States, and Europe. Korean and Japanese companies remain major global battery suppliers, while the United States and European Union are adding domestic factories. However, Europe, the United States, and Korea each remain far below China's share across key battery supply-chain stages.

South Korea Has Major Global Battery Companies

South Korea is home to several internationally important battery manufacturers, including:

• LG Energy Solution
• Samsung SDI
• SK On

Korean manufacturers have built factories in South Korea, North America, Europe, and other markets.

South Korea's importance is therefore larger than a simple count of batteries physically produced within Korean borders might suggest.

Korean companies have traditionally held a particularly strong position in European battery supply. The IEA reported that Korean manufacturers' share of the EU market fell from nearly 80% in 2022 to about 60% in 2024 as Chinese LFP batteries gained market share.

I distinguish between:

Country of manufacture: Where the cell factory is physically located.

Manufacturer domicile: Where the battery company is headquartered.

This distinction becomes increasingly important as battery companies build international factories.

Japan Remains Technologically Important

Japan has a long battery-manufacturing history.

Major Japanese companies have helped develop lithium-ion battery manufacturing for consumer electronics and vehicles.

Japan is also one of the few countries, along with South Korea, that retains a significant battery-material and component industry outside China. The IEA identifies Korea and Japan as the only other countries with notable midstream battery industries capable of providing some supply-chain diversification.

However, Japan's overall production scale is much smaller than China's.

The United States Is Expanding Production

The United States has been investing heavily in domestic battery manufacturing.

New or expanding battery facilities involve U.S., Korean, Japanese, and other manufacturers, often through joint ventures with automakers.

The United States and European Union together represented around 30% of global investment in clean-energy manufacturing during 2025, up from 15% in 2023. This investment is gradually making clean-energy supply chains more geographically diverse.

However, manufacturing investment should not be confused with current battery output.

China still accounted for more than 80% of global battery-cell production in 2025.

A factory announcement also does not mean that the factory is already producing cells at its planned capacity.

I separate:

• Announced capacity
• Factory construction
• Commissioned capacity
• Actual production

These figures can differ greatly.

Europe Is Building a Regional Battery Industry

Europe is also working to develop domestic battery manufacturing.

European automakers have strong incentives to establish closer battery supply as electric-vehicle production expands.

However, the region still depends substantially on Chinese, Korean, and Japanese battery companies.

The IEA reports that nearly all battery cells used worldwide are supplied by companies headquartered in China, Korea, or Japan.

This demonstrates how concentrated battery manufacturing remains even when factories themselves are becoming more geographically distributed.

Why Is China So Competitive in Battery Manufacturing?

China's advantage is not only scale. Cost and manufacturing efficiency also matter.

China's battery industry benefits from highly integrated supply chains, experienced factories, dense supplier networks, strong domestic demand, and high manufacturing efficiency. The IEA estimates that manufacturing efficiency explains more than 40% of the battery production cost gap between China and Europe, showing that China's advantage cannot be explained only by cheaper labor or energy.

Manufacturing Efficiency Matters

Modern battery-cell production requires extremely precise processes.

Factories must control:

• Electrode coating
• Drying
• Calendering
• Cell assembly
• Electrolyte filling
• Formation
• Aging
• Quality inspection
• Moisture
• Temperature
• Contamination

High defect rates can significantly increase cell cost.

Factories that operate at large scale and maintain high production yields can therefore achieve a major cost advantage.

The IEA's 2026 analysis estimates that manufacturing efficiency accounts for more than 40% of the direct cost difference between battery production in China and Europe.

Component Suppliers Are Close to Cell Factories

Battery manufacturing needs much more than lithium.

A lithium-ion cell may require:

• Cathode material
• Anode material
• Separator
• Electrolyte
• Copper foil
• Aluminum foil
• Cell casing
• Conductive additives
• Binders
• Battery management electronics

China has built industrial clusters where many of these suppliers operate relatively close to battery factories.

This can reduce transport, inventory, qualification time, and supply risk.

The country's strength is especially pronounced in active materials. China produced about 85% of EV battery cathode active material and more than 90% of anode active material in 2025.

LFP Strength Has Helped China

Lithium iron phosphate has become especially important for stationary batteries and lower-cost electric vehicles.

Chinese manufacturers developed a particularly strong LFP production ecosystem.

This matters because LFP has become the dominant chemistry in stationary BESS installations and an increasingly important EV chemistry.

China's advantage in LFP manufacturing has therefore supported both its vehicle and energy-storage industries.

Does China Also Dominate BESS Battery Manufacturing?

Yes. China's battery-production lead extends directly into battery energy storage systems.

China dominates many of the batteries used in BESS because stationary storage increasingly relies on LFP lithium-ion cells, an area where Chinese manufacturers have enormous production capacity. China also accounted for around 60% of global battery-storage capacity additions in 2025, creating a large domestic market for cells, modules, containers, and integrated BESS equipment.

BESS Uses the Same Broader Battery Supply Chain

An energy-storage battery is not completely separate from the EV battery industry.

Both industries require:

• Lithium-ion cells
• Cathode materials
• Anodes
• Separators
• Electrolytes
• Copper and aluminum
• BMS electronics
• Thermal management

The cell formats and design priorities can differ, but both benefit from large-scale lithium-ion manufacturing.

This gives Chinese stationary-storage suppliers access to a mature domestic component base.

China Also Has Major BESS Integrators

Chinese manufacturers have expanded beyond cell supply into complete storage systems.

Companies such as CATL, BYD, Sungrow, Trina Storage, Envision Energy, HyperStrong, and CRRC participate in different parts of the battery-storage market.

Their products may combine:

• LFP cells
• Battery racks
• BMS
• PCS
• Liquid cooling
• Fire protection
• EMS
• Containerized enclosures

This creates another advantage: battery manufacturing scale supports BESS manufacturing scale, and BESS deployment creates more battery demand.

Will China Continue Making Most of the World's Batteries?

China's lead is likely to remain substantial, but battery manufacturing is gradually becoming more geographically diverse.

China is likely to remain the world's largest battery producer for the foreseeable future, although the United States, Europe, India, and other regions are investing in new manufacturing. The IEA still places China at around 80% of lithium-ion battery supply-chain capacity today, indicating that diversification will take years rather than happening quickly.

Other Countries Are Investing Heavily

Governments increasingly view batteries as strategic products.

Battery production affects:

• Automotive manufacturing
• Grid reliability
• Renewable energy
• Data centers
• Defense and industrial supply chains
• Employment
• Trade balances

This is encouraging more local manufacturing.

The United States and European Union substantially increased their share of clean-energy manufacturing investment in 2025.

However, building factories is only part of the challenge.

New battery industries also need:

• Skilled workers
• Active-material production
• Mineral processing
• Equipment suppliers
• Stable electricity
• Customer demand
• High factory utilization
• Competitive manufacturing yields

Duplicating the entire Chinese supply-chain ecosystem is much harder than building one cell factory.

Chinese Companies Are Also Expanding Overseas

Another important trend is that global diversification does not necessarily mean declining influence for Chinese manufacturers.

A Chinese-headquartered battery company can establish factories in Europe, Southeast Asia, or other markets.

The resulting battery may be locally produced even though the manufacturer remains Chinese.

This is why future market analysis needs to distinguish three questions:

1. Where was the battery made?
2. Where is the manufacturer headquartered?
3. Where were the battery materials and components produced?

Each can produce a different market-share number.

Supply Concentration Creates Risk

The IEA identifies battery supply chains as highly geographically concentrated. China accounts for around 80% of lithium-ion battery supply-chain production capacity, while its share of some components is even higher.

This creates potential exposure to:

• Trade disputes
• Tariffs
• Export restrictions
• Shipping disruption
• Natural disasters
• Geopolitical tension
• Local-content requirements

The IEA estimates that one month without Chinese battery supply-chain exports could reduce electric-car factory output outside China by approximately $17 billion.

That illustrates why many governments are trying to diversify battery production even when locally manufactured batteries initially cost more.

My Insights: What Country Makes the Most Batteries

The answer is clearly China, but I think the scale of its lead is more important than simply identifying the country.

China makes the most batteries in the world. It produced more than 80% of global battery cells in 2025 and controls around 80% of lithium-ion battery supply-chain production capacity. Its advantage extends into cathode materials, anode materials, LFP technology, EV batteries, and stationary BESS, making China the center of today's global battery manufacturing ecosystem.

China's Advantage Is an Ecosystem Advantage

I would not describe China merely as the country with the most gigafactories.

Its advantage comes from connecting multiple industries:

Mineral processing → active materials → cells → packs → EVs/BESS → recycling

When these stages operate within one industrial ecosystem, manufacturers can reduce cost, accelerate product development, and solve supply problems more quickly.

This is harder for a new manufacturing region to reproduce than a single battery factory.

Battery Ownership and Battery Origin Will Become More Complicated

Future batteries will increasingly cross national boundaries.

A Korean company may produce a cell in the United States using active materials from Asia.

A Chinese battery company may manufacture cells in Europe.

An American BESS integrator may use cells manufactured by an overseas company.

I therefore avoid calling a battery "American," "Chinese," "Korean," or "European" without defining what the term means.

For procurement, I investigate:

Question	Why it matters
Where is the manufacturer headquartered?	Corporate and geopolitical exposure
Where is the cell made?	Tariffs and local-content rules
Where is the cathode produced?	Supply-chain dependence
Where is the anode produced?	Supply-chain dependence
Where is the pack assembled?	Local manufacturing eligibility
Where is the BESS integrated?	Service and project delivery
Who provides the warranty?	Long-term commercial risk

This level of detail is increasingly important for battery projects subject to domestic-content requirements.

China's Leadership Is Especially Important for BESS

BESS deployment increasingly relies on LFP batteries.

China has a very strong LFP manufacturing ecosystem, so growth in stationary storage reinforces the country's battery-production advantage.

The IEA reported that China also led global battery-storage additions in 2025 with around 60% of deployment.

This means China has both major production and major domestic consumption.

That combination supports continued manufacturing scale.

Diversification Will Happen, but Slowly

I expect the United States, Europe, South Korea, Japan, India, and other Asian markets to increase battery production.

However, China's current lead is extremely large.

A new battery factory outside China can reduce dependence on imported cells, but the factory may still depend on Chinese:

• Anode materials
• Cathode precursors
• Graphite processing
• Manufacturing equipment
• Other components

The IEA's 2026 analysis shows that China remains dominant across multiple battery supply-chain steps.

For that reason, I expect battery manufacturing to become more geographically diverse without China quickly losing its position as the world's largest battery producer.

Conclusion

China makes the most batteries, producing over 80% of global battery cells in 2025. Its integrated materials, cell, EV, and BESS supply chains give it a substantial global lead.
