CATL and BYD continued to lead the global electric vehicle (EV) battery market between January and September 2025, maintaining a combined market share of 54.5 percent, according to data released by SNE Research. Despite slightly lower individual shares compared to the previous period, both Chinese manufacturers posted strong year-on-year growth as global EV battery demand surged.
Global EV battery installations reached 811.7 GWh during the first nine months of 2025, up 34.7 percent from 602.4 GWh in the same period last year. CATL accounted for 297.2 GWh, representing a 31.5 percent increase from 226.0 GWh in 2024. This gave the company a 36.6 percent global market share, maintaining its position as the only supplier with more than 30 percent of global installations. However, this share was slightly below the 37.5 percent recorded in January–September 2024 and the 36.8 percent reported in January–August 2025.

BYD ranked second with 145.0 GWh of installed capacity, an increase of 45.6 percent compared with 99.6 GWh in the same period last year. Its global market share stood at 17.9 percent, up from 16.5 percent in January–September 2024, though marginally lower than 18.0 percent recorded for January–August 2025. The two Chinese manufacturers together supplied more than half of the global EV battery market, underscoring China’s continued dominance in the sector.
In third place, LG Energy Solution installed 79.7 GWh, marking a 14.7 percent year-on-year increase from 69.5 GWh a year earlier. The South Korean manufacturer’s market share stood at 9.8 percent, compared with 11.5 percent during the same period in 2024 and 9.7 percent as of August 2025. CALB (HKG: 3931) followed in fourth place with 39.0 GWh, translating to a 4.8 percent share, while SK On secured fifth position with 34.1 GWh and a 4.2 percent share.

Panasonic ranked sixth with 33.2 GWh and a 4.1 percent market share, followed by Gotion High-tech in seventh place with 30.0 GWh (3.7 percent), Samsung SDI in eighth with 22.7 GWh (2.8 percent), Eve Energy in ninth with 21.9 GWh (2.7 percent), and Svolt Energy in tenth with 20.4 GWh (2.5 percent).
Industry analysts noted that while CATL and BYD’s market shares saw minor fluctuations, their year-on-year volume growth remained robust, reflecting continued expansion in global EV production. South Korean and Japanese manufacturers retained stable positions in the rankings, but Chinese companies collectively accounted for over 70 percent of global EV battery installations in the first nine months of 2025 — highlighting China’s enduring advantage in EV battery supply chain capacity and cost efficiency.
