Half-yearly battery installation rankings in China for 2025 reveal a dominance by CATL and BYD, accounting for an impressive 66.6% of the market share.
China's Power Battery Market Shows Signs of Diversification
The power battery market in China, a global powerhouse, continues to be dominated by two key players, CATL and BYD, who together held a combined market share of approximately 66.6% in the first half of 2025 [1][2]. However, a closer look reveals a subtle yet significant shift towards a more diversified market.
CATL, the market leader, maintained its position with an installation volume of 128.6 GWh and a market share of 43.05%, while BYD followed closely with an installation volume of 70.37 GWh and a market share of 23.55% [1][2]. Despite their leading positions, both companies have experienced a slight decline in market share compared to the previous year, with CATL losing about 3.3 percentage points and BYD about 1.55 points [1][2].
This shift is due to the entry of new entrants and specialized firms, such as Geely's Jidian, Gotion Tech, CALB, EVE Energy, and others, who are gradually making their mark in the industry [1][2]. As a result, the top ten manufacturers' combined share has dropped from about 96% last year to 93.6% in H1 2025, indicating a gradual diversification of the market [2].
This trend is causing a gradual reduction in market concentration, with the top ten companies accounting for 94.2% of the installation volume in June 2025, down 1.8 percentage points from the previous year [2]. The overall market concentration remains strong, but the emergence of new players suggests a more competitive landscape.
The China power battery market installed about 299.6 GWh capacity in H1 2025, marking a year-on-year growth of 47.3% [1][2], indicating rapid overall market expansion that may support this diversification. Notably, CATL and BYD's losses in market share are happening despite absolute growth in their volumes, reflecting growth even faster at the mid-tier and smaller firms.
China's push for renewable energy and EV adoption, along with the continuing growth of the market, suggests ongoing expansion and room for more players [3]. Chinese firms control about 77% of global battery pack assembly capacity, with CATL and BYD accounting together for over half of the global EV battery market share, emphasizing China’s global dominance but also a competitive domestic landscape [4].
In conclusion, while CATL and BYD still dominate in scale and volume, the entry of specialized firms and newer companies is impacting market dynamics, slightly diluting the dominance of the traditional leaders and fostering competition. This dynamic is reshaping market concentration and potentially fostering innovation and competition within the sector [1][2][5].

- The growth in China's power battery market, fueled by the push for renewable energy and EV adoption, has attracted several new entrants and specialized firms, such as Geely's Jidian, Gotion Tech, CALB, EVE Energy, and others, who are gradually making their mark in the industry.
- The entry of these new players, like Geely's Jidian, Gotion Tech, CALB, EVE Energy, and others, into the power battery market has led to a gradual reduction in market concentration, with the top ten companies accounting for a slightly lower percentage of the market share compared to the previous year.
