Q1 2026 Global EV Battery Market: Chinese Firms Lead as Growth Slows to 9.1%

The global electric vehicle (EV) battery market saw a significant slowdown in the first quarter of 2026, with a growth rate of 9.1% compared to the 31.7% growth in 2025. This shift reflects a broader trend of the industry moving from rapid expansion to more stable and diversified growth.

Global EV Battery Market Overview

According to data from SNE Research, the total global EV battery installations reached 244.6 GWh in Q1 2026, a 9.1% increase year-over-year. This growth is significantly lower than the 31.7% growth seen in 2025, indicating a structural change in the demand for EVs globally.

Regional Demand Dynamics

• China: As the world’s largest EV battery market, China experienced a slowdown in EV sales, which put pressure on local companies like BYD. However, this also accelerated the overseas expansion of Chinese battery manufacturers.
• North America: The decline in EV sales in North America has put pressure on Korean and Japanese battery makers, such as LG, SK, and Panasonic. Automakers’ strategic adjustments have further reduced battery installation demand.
• Europe and Emerging Asian Markets: These regions continue to show growth, providing a significant boost to companies like CATL and LG Energy Solution, which are expanding their presence in these markets.

Corporate Performance and Market Leadership

The regional diversification of demand has directly influenced the performance of leading battery manufacturers. Chinese firms, particularly CATL and BYD, have maintained their dominant positions, while Korean and Japanese companies face increasing pressure.

Chinese Firms Continue to Lead

CATL, the world’s largest EV battery manufacturer, reported a 15.2% increase in installations, reaching 99.5 GWh. This growth, well above the industry average, solidifies CATL’s market share at 40.7%. The company’s success is driven by strong domestic sales, particularly from brands like AITO, and expanding international partnerships with Toyota, Kia, and Skoda.

Korean and Japanese Companies Under Pressure

Korean battery makers, including LG, SK, and Samsung SDI, have seen their market shares shrink. Panasonic, while maintaining a steady growth, is focusing on diversifying its customer base and transitioning to new technologies.

Implications for Western Investors

The slowdown in global EV battery growth and the continued dominance of Chinese firms highlight the need for Western investors to closely monitor the evolving landscape. The shift towards more diversified and high-quality competition means that companies with a strong global presence and robust technology will be better positioned to succeed.
