China's Leading Battery Installation Companies in the First Half of 2025 - CATL and BYD control a collective 66.6% of the market share
In the first half of 2025, China's power battery market has shown signs of gradual diversification, despite the continued dominance of CATL and BYD. The two companies accounted for 66.6% of the market, a slight decrease from the previous year for both companies.
CATL held an installation volume of 128.6 GWh and a market share of 43.05%, while BYD had an installation volume of 70.37 GWh and a market share of 23.55%. This decrease in market share for the top two companies indicates the emergence of competition from other players.
The top ten companies collectively held a 93.6% share in the market, a decrease of 2.5 percentage points year-on-year. This decline in market concentration suggests a more competitive landscape in the power battery market.
Companies like CALB, Gotion Tech, and Great Wall's Svolt posted noticeable installation volumes, contributing to increased diversity among top suppliers. The market shift is described as a gradual move towards a "more diversified industrial ecosystem," with new entrants and specialized firms finding footholds despite the strong presence of CATL and BYD.
The market expansion is evident in the cumulative power battery installations, which reached 299.6 GWh in H1 2025, a 47.3% year-on-year increase. This growth indicates a rapidly expanding market that can support more manufacturers.
The industry is experiencing a gradual decline 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. This trend suggests that while leading companies still hold significant market power, new entrants and specialized firms are gradually finding their footing, leading to a more diversified industrial ecosystem.
