In the first half of 2025, Chinese battery manufacturers CATL and BYD seized notable market shares, with CATL controlling 37.9% and BYD holding 17.8% of the global electric vehicle (EV) battery market.
In the first half of 2025, the global EV battery market experienced significant growth, with total installations reaching 504.4 GWh, a 37.3% year-on-year increase [1][2]. The market is driven by the increasing demand for electric vehicles worldwide.
Leading the pack is CATL, the world's top EV battery supplier, with a market share of 37.9% [1][2]. The Chinese company's installations reached 190.9 GWh, marking a 37.9% year-on-year increase [1][2]. CATL remains the only supplier with a share above 30%.
BYD follows closely behind, holding a 17.8% market share [1][2]. The company's EV battery shipments reached 89.9 GWh, a 58.4% year-on-year increase [1][2].
South Korea's LG Energy Solution ranks third, with a 9.4% market share [1]. However, this is a decline from the 12.3% share the company held in the same period last year and also a drop from the 10.0% share it held in January-May 2025 [1].
Other players in the market include CALB, Gotion High-tech, SK On, Panasonic, Samsung SDI, Eve Energy, and Svolt Energy. While these companies have smaller shares and typically rank below the top three, exact numbers for many of these are not detailed in the sources [1][2][5].
It's worth noting that in the Chinese market specifically, CALB and Gotion High-tech showed growth in July 2025. CALB held about 8.4% share, and Gotion about 4.8% in the month of July, indicating a rising prominence [5].
The data for H1 2025 shows the dominance of Chinese battery makers CATL and BYD globally. South Korea's LG Energy Solution holds the third spot. Other competitors are more prominent in regional or monthly data but less so globally during H1 2025 [1][2][5].
Here's a breakdown of the market share and installed capacity for H1 2025:
| Company | Market Share (H1 2025) | Installed Capacity (GWh) | Comments | |-------------------|------------------------|-------------------------|------------------------------------------------| | CATL | 37.9% | 190.9 | Largest by far, only above 30% share | | BYD | 17.8% | 89.9 | Fast growing, up from 15.4% in previous year | | LG Energy Solution| 9.4% | 47.2 | Third largest, declined from 12.3% previous year| | CALB | ~8.4% (July China) | Not specified globally | Increasing market share in China (July data) | | Gotion High-tech | ~4.8% (July China) | Not specified globally | Growing, ranks fourth in China (July data) | | SK On | Not specified | | Data not provided explicitly | | Panasonic | Not specified | | Data not provided explicitly | | Samsung SDI | Not specified | | Data not provided explicitly | | Eve Energy | Not specified | | Data not provided explicitly | | Svolt Energy | Not specified | | Data not provided explicitly |
In June 2025, CATL and BYD dominated the Chinese EV battery installations, with CATL holding a 43.67% share and BYD holding a 21.47% share [3].
