China Already Makes More EV Batteries Than the World Needs as Oversupply Crisis Deepens
By CII (China Industry Intel) – Contributing Analyst | June 24, 2026
China now produces more electric vehicle batteries than the entire world can consume, creating an oversupply crisis that is reshaping the global battery industry with profound implications for manufacturers, automakers, and consumers worldwide. According to BloombergNEF’s latest analysis, China’s annual battery manufacturing capacity has surged past 1,200 gigawatt-hours (GWh) — a figure that exceeds total global demand for lithium-ion batteries across all applications, including electric vehicles, stationary energy storage, and consumer electronics. The oversupply, driven by aggressive capacity expansion from industry giants CATL and BYD, is fueling a price war that has sent battery cell prices tumbling to historic lows while threatening the viability of smaller producers both in China and internationally.
The scale of the imbalance is staggering. BloombergNEF data reveals that global lithium-ion battery demand reached approximately 850 GWh in 2025, with electric vehicles accounting for roughly 75% of that total. China alone, however, produced an estimated 900 GWh of batteries in the same year — more than the entire world’s EV battery requirements. The country’s production capacity has been growing at a compound annual rate of over 40% since 2020, far outpacing the already-impressive growth rate of EV adoption. With additional capacity coming online from South Korea, Japan, Europe, and North America, the global battery market is confronting a structural surplus that most industry analysts believe will persist through at least 2028.
The roots of this overcapacity crisis trace back to the post-pandemic surge in EV demand and the Chinese government’s strategic push to dominate the battery supply chain. Between 2020 and 2023, Chinese battery manufacturers announced over $100 billion in new factory investments, encouraged by generous provincial subsidies, preferential land allocations, and Beijing’s broader ambition to control the key technology of the energy transition. CATL, the world’s largest battery maker with approximately 37% global market share, alone operates over 500 GWh of production capacity and has plans to reach 800 GWh by 2027. BYD, the second-largest producer and China’s top EV manufacturer, has been expanding its vertically integrated battery operations at an equally aggressive pace, with its FinDreams battery unit now supplying both BYD vehicles and external automakers including Tesla, Toyota, and Mercedes-Benz.
The Battery Price Collapse: Winners and Losers
The most immediate consequence of the oversupply has been a dramatic decline in battery prices. According to BloombergNEF’s annual battery price survey, the volume-weighted average price of lithium-ion battery packs fell to $107 per kilowatt-hour (kWh) in 2025, down from $139/kWh in 2023 and over $1,200/kWh in 2010. In China, where competition is fiercest, prices have fallen even further — some contracts for lithium iron phosphate (LFP) cells are reportedly being struck at below $50/kWh, a level that was considered unthinkable just two years ago. The price collapse has accelerated the EV industry’s long-sought goal of achieving cost parity with internal combustion engine vehicles, but it has come at a devastating cost to battery manufacturers’ profitability.
CATL, despite its market dominance and economies of scale, reported its first year-over-year revenue decline in 2025 as falling prices more than offset volume growth. The company’s net profit margin, which exceeded 12% in 2022 amid tight battery supply, compressed to below 7% by early 2026. Smaller Chinese producers have fared far worse: at least a dozen second- and third-tier battery manufacturers have either filed for bankruptcy, suspended operations, or been acquired by larger rivals since mid-2024. The consolidation wave has been especially severe among lithium iron phosphate (LFP) producers, where product commoditization and minimal differentiation have turned the segment into a pure cost-competition game that only the largest players can survive.
For global automakers, the battery price collapse presents both an opportunity and a strategic dilemma. Lower battery costs are accelerating the business case for EV production, enabling automakers to offer electric vehicles at more competitive prices and potentially accelerating the transition away from internal combustion engines. However, the overconcentration of battery supply in China raises profound concerns about supply chain resilience and geopolitical vulnerability. European and North American automakers that have invested billions in local battery production through joint ventures with Korean and Japanese manufacturers are watching with alarm as their Chinese competitors undercut them by 30-50% on price. The situation has prompted calls in both Brussels and Washington for stronger trade protections, including potential tariffs on Chinese battery imports that would mirror the duties already imposed on Chinese EVs.
CATL vs. BYD: The Battle for Supremacy
The oversupply crisis has intensified the long-running rivalry between CATL and BYD, the two titans of China’s battery industry. While both companies continue to expand capacity, their strategies for navigating the downturn differ markedly, reflecting their distinct positions in the broader EV and battery ecosystem.
CATL, as a pure-play battery manufacturer, is pursuing a strategy of technological differentiation to maintain pricing power. The company has invested heavily in next-generation battery technologies, including its Qilin battery with claimed energy density of 255 Wh/kg, its sodium-ion battery lineup for cost-sensitive applications, and its condensed-matter battery technology aimed at the aviation and premium EV segments. CATL is also aggressively expanding its battery swap station network — branded EVOGO — and its stationary energy storage business, both of which provide alternative revenue streams less exposed to the brutal price competition in automotive cells. The company’s international expansion, including factories in Hungary, Germany, Indonesia, and potentially the United States through its Ford licensing agreement, is designed to capture demand in markets where Chinese price competition is less direct and where local content requirements create protective moats.
BYD, by contrast, benefits from its unique position as both a battery manufacturer and the world’s largest EV producer. The company’s vertical integration means that a significant portion of its battery output is consumed internally, insulating its battery division from the worst effects of the market downturn. BYD’s FinDreams battery unit has also been winning external customers at a remarkable pace, leveraging the company’s proven manufacturing scale and the demonstrated reliability of its Blade Battery LFP technology. BYD’s ability to cross-subsidize its battery business with profits from its EV and electronics divisions gives it a staying power that few competitors can match. The company’s recent expansion into commercial vehicles, energy storage, and rail transit further diversifies its battery demand base.
The competitive dynamics between CATL and BYD are reshaping the global battery supply chain. Automakers are increasingly playing the two giants against each other to secure the most favorable pricing, while simultaneously developing multi-supplier strategies to avoid over-dependence on any single source. Tesla, which sources batteries from both CATL and BYD as well as from Panasonic and its own in-house 4680 cell production, exemplifies this approach. Other automakers, including Volkswagen, BMW, and General Motors, are following similar strategies, creating a complex web of supply relationships that spans the globe.

The Global Dimension: American and European Battery Ambitions Under Threat
China’s battery oversupply is having far-reaching effects beyond its borders, directly threatening the viability of nascent battery industries in North America and Europe. Both regions have committed tens of billions of dollars to building domestic battery manufacturing capacity, motivated by energy security concerns and the desire to capture the economic benefits of the energy transition. The United States, through the Inflation Reduction Act’s Section 45X production tax credits and the Department of Energy’s Advanced Technology Vehicles Manufacturing loan program, has catalyzed over $80 billion in planned battery manufacturing investments. Europe, through its Important Projects of Common European Interest (IPCEI) framework and various national subsidy programs, has mobilized a similar amount.
However, the flood of low-cost Chinese batteries is making the economics of these Western investments increasingly questionable. A battery cell that costs $55/kWh to produce in China can be manufactured for $75-85/kWh in the United States even after accounting for IRA subsidies, and for $80-95/kWh in Europe. This 30-50% cost gap is not easily closed through incremental efficiency improvements or scale economies — it reflects structural advantages in China’s battery supply chain, including lower energy costs, more streamlined environmental permitting, a deep pool of experienced engineers and operators, and most importantly, an upstream materials processing industry that China has spent two decades building into a globally dominant position.
The implications for Western battery startups and scale-ups are dire. Companies like Britishvolt (UK), Freyr Battery (Norway), and Italvolt (Italy) have already either collapsed or dramatically scaled back their ambitions, unable to compete with the pricing pressure emanating from China. Even established players like Northvolt, Europe’s flagship battery champion, have faced significant headwinds: the company announced a strategic review in late 2025 that included production delays at its German and Canadian facilities and a renewed focus on its core Swedish operations. The US market has proven somewhat more resilient due to the combination of IRA subsidies, strong domestic EV demand, and the complexity of importing Chinese batteries given the current trade environment, but even American producers acknowledge that sustained Chinese overcapacity represents an existential competitive threat.
The Raw Materials Paradox: Low Prices Despite Supply Chain Concentration
One of the most striking features of the current battery oversupply crisis is that it is occurring alongside historically low prices for key battery raw materials. Lithium carbonate prices, which spiked to over $80,000 per metric ton in late 2022 during the post-pandemic supply squeeze, have since collapsed to approximately $12,000-15,000 per ton — below the marginal cost of production for many high-cost mining operations. Similarly, cobalt prices have fallen to around $15 per pound, roughly a third of their 2022 peak, while nickel prices have declined significantly from their March 2022 short-squeeze highs.
Normally, low raw material prices would help alleviate margin pressure on battery manufacturers, but the depth of the oversupply means that input cost savings are being more than fully passed through to customers in the form of lower cell prices. This dynamic is creating a crisis of its own in the upstream mining and materials processing sector: major lithium producers including Albemarle and SQM have announced production cuts and project deferrals, while dozens of junior mining companies that raised capital during the 2022 boom are now struggling to survive. The situation is particularly acute for Western lithium projects, which typically have higher cost structures than established operations in Chile, Argentina, and Australia, let alone China’s domestic lithium production from lepidolite and brine sources.
Paradoxically, the current environment of oversupply and low prices may be setting the stage for the next cycle of shortage and price spikes. The battery industry’s historical boom-bust pattern suggests that sustained low prices inevitably lead to underinvestment in new capacity, which eventually results in supply tightness when demand catches up. With EV adoption still in its early stages globally — EVs accounted for approximately 18% of global new car sales in 2025, leaving enormous room for growth — the long-term demand trajectory for batteries remains strongly upward. BloombergNEF projects that annual global battery demand could reach 3,000 GWh by 2030 and over 5,000 GWh by 2035, implying that even China’s current overcapacity could be absorbed over time if demand growth continues at expected rates. The question is how many of today’s battery manufacturers will survive long enough to see that demand materialize.
