Chinese manufacturers of electric vehicle batteries have increased their global market share to over 70%
Chinese battery manufacturers consolidated their global dominance in 2025, increasing the combined share of installed car battery capacity to more than 70% from less than 50% in 2021, while South Korean competitors lost ground, in particular due to their heavy reliance on the weakening electric vehicle market in the United States, according to Nikkei.
CATL remained the global leader with a 39.2% share, up 1 point from 2024, and recorded a record net profit of 72.2 billion yuan, up 42%, due to a wide range of batteries, strong demand in China, and the growth of European customers such as Volkswagen and Mercedes—Benz. In 2025, global installed battery volumes for electric vehicles and hybrid vehicles increased by 32% to 1,187 gigawatt-hours, with China accounting for about 60% of the market.
Six of the world's top 10 battery manufacturers were Chinese, including BYD, CALB and Gotion, whose shares also increased. BYD continued to supply batteries for its own cars, while expanding sales to external customers such as Xiaomi and Stellantis. Instead, the combined share of South Korean manufacturers fell to 15.3%, which is about half the level of 2021. LG Energy Solution's net profit fell by 76%, while SK On and Samsung SDI suffered losses. The Japanese Panasonic group took the seventh place with a share of less than 4%.
