EV Battery Market Share in First Half of 2025: CATL Leads with 37.9%, Followed by BYD with 17.8%
The global electric vehicle (EV) battery market experienced significant growth in the first half of 2025, with total installations reaching 504.4 gigawatt-hours (GWh), a 37% increase from the same period in 2024.
In this dynamic landscape, several key players emerged as leaders. Chinese battery company Contemporary Amperex Technology Co. Limited (CATL) maintained its top position with a market share of 37.9%, installing 190.9 GWh of batteries, marking a 37.9% increase year-over-year.
BYD, another Chinese company, held the second position with a market share of 17.8%, shipping 89.9 GWh, which represents a 58.4% year-over-year increase.
South Korea's LG Energy Solution ranked third with a market share of 9.4%, installing 47.2 GWh. While this is a slight decrease from its 12.3% share in the same period last year, it still represents a 4.4% year-on-year increase.
Data from South Korean market research firm SNE Research also revealed that China's CALB ranked fourth with a 4.3% share, while China's Eve Energy ranked ninth with a 2.7% share. Japan's Panasonic ranked sixth with a 3.7% share, up two places from January-May, and South Korea's Samsung SDI ranked eighth with a 3.2% share. Svolt Energy from China ranked tenth with a 2.6% share.
The market shares for Gotion High-tech, SK On, and Eve Energy were not detailed in the available data, but these companies are part of the broader EV battery market landscape, with some of them likely to hold smaller shares.
The dominance of CATL and BYD is partly due to their cost competitiveness and scale, particularly in China, where lithium iron phosphate (LFP) batteries have gained significant market share. The overall market continues to grow rapidly, driven by increasing demand for electric vehicles and supportive policies in various regions.
BYD is a company with multiple stock symbols, including HKG: 1211 and OTCMKTS: BYDDY. CATL, on the other hand, is a Chinese battery company with the stock symbol SHE: 300750.
As the global EV market continues to evolve, it will be interesting to see how these players' market shares change in the coming months and years.
