China’s EV Battery Makers Widen Lead to over 70% Global Share

Why It Matters

China’s battery dominance reshapes global EV supply chains, pressuring rivals on price and capacity, while the slowdown in South Korea highlights the geopolitical risk of relying on a single market.

Key Takeaways

• Chinese battery makers hold over 70% global capacity.
• CATL profit hit $10.5 billion, up 42%.
• South Korean share fell to 15.3%, losing half since 2021.
• LG Energy Solution profit dropped 76% to $53.9 million.
• Chinese firms expand overseas to hedge domestic slowdown.

Pulse Analysis

China’s battery sector has become the linchpin of the global electric‑vehicle ecosystem. By leveraging massive state subsidies, a vertically integrated supply chain, and aggressive capacity expansion, firms like CATL and BYD have driven the worldwide market share past the 70% threshold. This scale advantage translates into lower unit costs, tighter price margins for automakers, and a stronger negotiating position in Europe and North America, where local rivals struggle to match Chinese volume and technology pace.

The decline of South Korean battery makers underscores how policy volatility can erode market position. The reversal of U.S. EV incentives under the current administration stripped LG Energy Solution, SK On, and Samsung SDI of a critical revenue stream, precipitating profit slumps and workforce reductions. Their combined share fell by three points, and LG’s earnings shrank to a fraction of CATL’s, exposing the fragility of a strategy overly dependent on a single export market. Japanese players, exemplified by Panasonic, remain marginal, with sub‑4% share and delayed plant roll‑outs, further cementing China’s lead.

Looking ahead, Chinese manufacturers are diversifying production abroad to mitigate domestic demand risks as subsidies wane and sales dip 28% year‑on‑year early in 2026. New facilities in Hungary, Southeast Asia, and Europe aim to align with local content rules and reduce logistics costs. While the Chinese market may temper, the global appetite for EVs remains robust, ensuring that Chinese battery firms will continue to dictate pricing, technology standards, and supply‑chain dynamics for the foreseeable future.
