China controls over 70% of global EV batteries, led by CATL and BYD

Chinese battery makers tightened their grip on the global electric vehicle battery market in 2025, accounting for more than 70% of worldwide installations, led by industry giants CATL and BYD, as global EV demand continued to expand rapidly.

Global EV battery installations reached 1,187 gigawatt-hours (GWh) in 2025, a 31.7% year-on-year increase from 901.4 GWh in 2024, according to data released Wednesday by SNE Research. The figures underscore both strong market growth and increasing concentration among leading suppliers.

CATL remained the world’s largest EV battery supplier, with installations totaling 464.7 GWh in 2025, up 35.7% from a year earlier. The company captured a 39.2% global market share, making it the only battery manufacturer with more than 30% of the global market.

BYD ranked second, installing 194.8 GWh of EV batteries in 2025, a 27.7% increase from 2024. BYD held a 16.4% market share, slightly lower than the previous year but sufficient to firmly maintain its second-place position.

Together, CATL and BYD installed 659.5 GWh of EV batteries in 2025, accounting for 55.6% of global installations, reinforcing their central role in China’s overall dominance of the sector.

South Korea’s LG Energy Solution ranked third, with 108.8 GWh of installations, an 11.3% year-on-year increase. Its global market share, however, declined to 9.2%, down from 10.9% in 2024.

China’s CALB placed fourth with 62.8 GWh of installations and a 5.3% share, followed by China’s Gotion High-tech at 4.5%. South Korea’s SK On ranked sixth with a 3.7% share.

Japan’s Panasonic, China’s Eve Energy, South Korea’s Samsung SDI, and China’s Svolt Energy rounded out the global top ten, each holding between 2.4% and 3.7% market share in 2025. Rankings shifted modestly during the January–November period, when Svolt Energy briefly edged ahead of Samsung SDI.

The data highlights accelerating global EV adoption alongside growing concentration among a small group of dominant battery suppliers, as scale and technology advantages continue to shape the market.
