Why China Owns ~75% of EV Battery Production

A modern EV is, by cost and by strategic importance, mostly a battery. China makes most of the world's batteries — and refines most of the world's battery minerals even when the mining happens elsewhere. Here is how that concentration came to be and how long unwinding it actually takes.

Verified May 2026.

The headline numbers

Per the International Energy Agency's 2025 Global EV Outlook and BloombergNEF tracking data, the rough state of play in 2025–2026 is:

~75% of lithium-ion cell production capacity is in China. The share rises above 80% for LFP cells specifically and is closer to 60–65% for NMC.
Korea is the next-largest producer at ~15% (LG Energy Solution, Samsung SDI, SK On), Japan around 5% (Panasonic), and US/EU together about 5%.
China refines roughly 60–70% of global lithium, 70% of cobalt, around 75% of nickel sulfate for batteries, and the overwhelming majority of battery-grade graphite.
Two Chinese companies dominate cell production: CATL (Contemporary Amperex Technology Co. Limited), headquartered in Ningde, Fujian, and BYD (FinDreams Battery), headquartered in Shenzhen. Together they account for over half of global EV cell shipments.

A Ford Mustang Mach-E built in Mexico, a Hyundai Ioniq 5 built in Georgia, a Tesla Model 3 built in Fremont — every one of these has cells that either came from China or that came from Korea using Chinese-refined inputs. The supply chain is global; the dominance is concentrated.

Why China — the policy backstory

The concentration is not accidental. From the early 2010s, successive Chinese five-year plans identified new-energy vehicles and battery cell manufacturing as strategic industries. The toolkit included:

Provincial-level investment subsidies for cell plants, sometimes covering most capex.
Consumer purchase subsidies for NEVs through 2022, plus license-plate access advantages in major cities (Beijing, Shanghai, Shenzhen) that make NEVs much cheaper to register than ICE vehicles.
A “white list” of approved battery suppliers from 2015 to 2019 that effectively excluded foreign cell producers from cars eligible for subsidies — protecting CATL and BYD during their critical scaling years.
State-owned bank financing for upstream mineral refining and cathode material plants.
Outbound investment in Indonesian nickel, DRC cobalt, Australian and South American lithium, and African graphite — locking in long-term supply.

The result: by the time Western automakers fully committed to EVs around 2020–2022, the supply chain to do so at scale was already in China.

CATL and BYD: the two giants

CATLis the world's largest battery cell producer with roughly 35–38% global share. CATL supplies cells to Tesla (Shanghai factory and a growing share of US-bound inventory), BMW, Mercedes, Ford (Mustang Mach-E, F-150 Lightning standard range), Hyundai, Volkswagen, and most major Chinese OEMs. CATL is the cell-supplier-of-record for the modern EV industry — and CATL's licensing arrangement with Ford for a Michigan LFP plant became a political flashpoint over IRA eligibility.

BYD (FinDreams Battery)is the second-largest, around 16–18% global share. BYD's production is predominantly captive — most cells go into BYD's own vehicles — but it also supplies Toyota, Tesla (Berlin), and a growing number of OEMs. The Blade battery, a long, thin LFP cell architecture that improves pack-level energy density and thermal safety, is BYD's signature product.

Below CATL and BYD sit a tier of mid-sized Chinese producers: CALB, EVE Energy, Gotion High-Tech, Sunwoda, and others. Each would, by Western standards, be a major industrial company. In China they are tier-two suppliers.

Korean and Japanese competitors

Outside China, three Korean companies and one Japanese company are the credible cell producers:

LG Energy Solution — the largest non-Chinese producer; major US plants in Michigan, Tennessee, and (joint-venture) Ohio (with GM) and Georgia (with Hyundai). Supplies GM, Ford, Hyundai-Kia, Volkswagen, Stellantis.
Samsung SDI — strong in NMC for premium vehicles; supplies Rivian, BMW, Stellantis, Audi. Joint ventures with Stellantis in Indiana and Hyundai in the US.
SK On — supplies Ford F-150 Lightning long range and Hyundai/Kia. JV plants with Ford (BlueOval SK in Kentucky and Tennessee) and Hyundai (Georgia).
Panasonic — the historic Tesla cell partner, still supplying Model 3/Y long-range in the US from Nevada and Kansas plants. Now broadening to Lucid, Mazda, and others.

The Korean and Japanese producers can build cells outside China. What they cannot fully do is build them without Chinese inputs — cathode active material, lithium hydroxide, graphite, and other links in the chain remain heavily China-dependent.

The Inflation Reduction Act's battery rules

The IRA, signed in August 2022, set up a complex two-tier structure for the $7,500 consumer EV tax credit. Half of the credit ($3,750) was tied to battery component sourcing — a rising percentage of the value of components had to be manufactured or assembled in North America. The other half was tied to critical mineral sourcing — a rising percentage of the value of critical minerals had to be extracted, processed, or recycled in the US or in countries with US free-trade agreements. A separate “Foreign Entity of Concern” (FEOC) restriction barred credit eligibility for vehicles containing battery components manufactured by entities under Chinese, Russian, North Korean, or Iranian control.

The intent was to onshore the battery supply chain by making domestic and friendshore production a prerequisite for the consumer credit. The effect was a wave of announced US battery plant investment between 2022 and 2025 — Ford BlueOval City, GM-LG Ultium plants, Hyundai-LG and Hyundai-SK plants in Georgia, Tesla's Nevada expansion, and dozens more.

Then the broader IRA EV consumer credit sunset on September 30, 2025. Several of the announced plant projects are continuing (driven by independent corporate strategy and state-level incentives) but the strongest demand pull has weakened. As of May 2026 the build-out is partial and slower than the 2023 projections assumed.

Mineral refining: the deeper bottleneck

A modern NMC cell needs lithium, nickel, cobalt, manganese, copper, aluminum, graphite, plus separator and electrolyte materials. Each of these needs to be mined, refined to battery grade, processed into cathode or anode active material, formed into electrodes, and assembled into cells. The mining is more globally distributed than people assume; the refining and active-material steps are heavily Chinese.

A worked example: lithium. Australia mines roughly half of global lithium as spodumene concentrate. That concentrate is shipped — overwhelmingly to China — for conversion into battery-grade lithium hydroxide and carbonate. Chile and Argentina produce lithium from brine and some local conversion exists, but the dominant flow is Australian rock to Chinese chemistry. The US has a small lithium refining industry (Albemarle's Silver Peak, Nevada; new projects in North Carolina and Arkansas) but the catch-up is at least a decade out from displacing meaningful Chinese capacity.

The same pattern holds for graphite (mined in Mozambique, Madagascar, and China; refined in China) and for cathode active material like nickel-cobalt-manganese hydroxide. The IEA estimates Chinese share of global cathode active material production at over 80%.

How long to catch up

A reasonable composite of timelines from the IEA, BloombergNEF, DOE's Office of Manufacturing and Energy Supply Chains, and private sector analysts:

Cell production: the US can plausibly reach 30–40% of domestic demand by 2028–2030 under the announced but partly stalled plant build-out. Reaching parity with domestic demand is a 2030–2035 project.
Cathode and anode active material: 2032–2038 for a non-trivial US share. Multiple announced US cathode plants are still in permitting or early construction.
Battery-grade mineral refining: 2035–2045 for the US and EU to reach material non-China share. Permitting cycles for refining facilities in the US and EU are measured in years, not months, and the projects compete with a Chinese cost structure built on 15 years of specialization.

The optimistic case requires sustained policy support across multiple US administrations, sustained capital availability, successful permitting reform, and willingness to accept higher near-term battery costs while the domestic industry scales. None of those are guaranteed.

What it means for US EV buyers

Three practical implications:

1. Cell origin is on your window sticker. Many automakers now disclose battery cell origin on Monroney stickers and online configurators, partly in response to the IRA FEOC rules. If supply-chain origin matters to you, the information is available — though “cells from Korea” does not mean “not China-fed”.

2. LFP is here to stay. The chemistry BYD scaled in China is now the standard for affordable long-life packs everywhere — including in US-market Teslas, the Ford Standard Range, the Chevy Equinox EV, and several Hyundai-Kia trims. LFP is not a Chinese-only chemistry, but the cost curve and manufacturing know-how started there. See our EV vs gas TCO calculator to see how battery longevity (where LFP has an edge) flows through to total-cost-of-ownership.

3. Expect more Chinese components, fewer Chinese brands. Through 2028 the most likely US-market pattern is more cars containing Chinese-supplied cells, cathode material, or refining inputs (sometimes via Korean or Japanese intermediaries), while finished Chinese-brand vehicles remain blocked by the tariff and connected-vehicle stack discussed in our tariff explainer.

Frequently asked questions

What share of global EV batteries does China make?+

Roughly 75% of global lithium-ion cell production capacity sits in China as of the IEA's 2025 Global EV Outlook, with that share running about 80%+ on LFP cells specifically and somewhat lower on NMC. Korean producers (LG Energy Solution, Samsung SDI, SK On) account for most of the rest, with Japan's Panasonic and a small but growing US/EU contribution. Even cells built in Europe and the US often use cathode active material, separators, and other components sourced from China.

What's the difference between LFP and NMC chemistry?+

LFP (lithium iron phosphate) uses iron and phosphate for the cathode; NMC (nickel-manganese-cobalt) uses nickel, manganese, and cobalt. LFP is cheaper, longer-lived in cycles, safer in thermal abuse, and tolerates 100% state-of-charge habits — but has lower energy density and worse cold-weather performance. NMC has higher energy density and better cold performance but is more expensive and uses materials with more supply-chain risk. The industry has moved toward LFP for standard-range vehicles (Tesla SR Model 3/Y, Ford Standard Range, Chevy Equinox EV, almost all BYD products) and reserves NMC for long-range and performance trims.

Why does mineral refining matter as much as mining?+

Australia mines about half the world's lithium, but China refines roughly 60% of it into battery-grade lithium carbonate and hydroxide. Indonesia and the Philippines lead in nickel mining, but China refines much of the nickel sulfate used in cathodes. Cobalt is mined predominantly in the DRC and refined predominantly in China. Graphite mining is more globally distributed but refining capacity for battery-grade synthetic and natural graphite is overwhelmingly Chinese. Without the refining step, raw mined material can't go into a cell. The refining concentration matters more than the mining concentration.

What did the Inflation Reduction Act battery rules actually do?+

The IRA's $7,500 consumer EV tax credit was split into two $3,750 halves: one for battery component sourcing, one for critical minerals sourcing. To qualify, a rising percentage of battery components had to be manufactured or assembled in North America, and a rising percentage of critical minerals had to be extracted/processed in the US or in countries with US free-trade agreements. The intent was to onshore the battery supply chain. The reality has been mixed: it drove tens of billions in announced US battery plant investment (LG, Samsung, Panasonic, Ford, GM, Hyundai-Kia, plus new entrants) but the credit largely expired on September 30, 2025 alongside the broader IRA EV credit rollback, removing the strongest near-term incentive to complete those projects.

How long until the US and EU catch up?+

The credible timeline for the US reaching 30–40% of its own battery cell supply is 2028–2032 under the announced (but partly stalled) IRA-era plant build-out. Catching up on cathode active material, anode material, separators, electrolyte, and especially mineral refining is a longer project — 2032–2040 by most credible analyses, and only if sustained policy and capital are applied. China has a 15-year head start built on tens of billions of state and private investment, established workforce, and integrated downstream demand from the world's largest EV market. The catch-up is possible but slow.

Could the US simply import cells from Korea instead of China?+

Largely yes — and largely already does. Most US-built EVs run Korean cells (LG, Samsung, SK On). The catch is that Korean cell producers depend heavily on Chinese cathode active material, lithium hydroxide, and graphite. A clean Korea-only supply chain is not what exists today; what exists is a Korea-finished, China-fed supply chain. Building a non-China cathode and refining base is the part the IRA was trying to accelerate.
