Global EV Battery Market in 2026: CATL and BYD Extend Leadership Despite Diverging Growth

The global EV battery market continued its upward trajectory during the first four months of 2026, with total battery usage reaching 352.7 GWh, representing a 13.8% increase compared to the same period last year. Market leadership remained firmly in the hands of CATL and BYD, although the two companies delivered contrasting performance trends. While CATL expanded both installations and market share, BYD experienced a modest decline in battery deployment volumes but successfully retained its position as the world's second-largest EV battery supplier.

CATL Strengthens Global Leadership Position

CATL maintained its status as the largest EV battery manufacturer globally, recording battery installations of 141.4 GWh between January and April 2026. This represented a strong year-on-year increase of 19.8%, outperforming the overall market growth rate. The company's market share reached 40.1%, improving from 38.1% during the corresponding period in the previous year. Although slightly lower than its 40.7% share recorded during the first quarter of 2026, CATL continued to consolidate its leadership position across the global electric vehicle battery landscape.

BYD Retains Second Position Despite Volume Decline

BYD remained the second-largest battery supplier worldwide, achieving total installations of 50.0 GWh during the January-April period. However, the company experienced a 2.4% year-on-year decline in battery usage. Its global market share stood at 14.2%, lower than the 16.5% recorded a year earlier. Despite this reduction, BYD improved from the 13.7% share reported for the January-March period, indicating some recovery momentum as the year progressed while maintaining a strong position in the global rankings.

Global EV Battery Market Share of Leading Companies

Chinese Manufacturers Expand Industry Influence

The combined market share of CATL and BYD reached 54.3%, highlighting the significant influence of Chinese companies in the EV battery sector. Additional growth from Chinese battery producers further strengthened this position. CALB secured fourth place globally with 18.1 GWh of installations and an impressive 39.3% year-on-year growth rate. Gotion High-tech ranked fifth with 15.6 GWh and a 30.2% increase in installations. These performances reflected the continuing competitiveness and scale advantages enjoyed by leading manufacturers in China.

South Korean and Japanese Suppliers Face Competitive Pressure

South Korea-based LG Energy Solution held third place globally with 32.0 GWh of battery installations. While the company recorded an 8.3% increase in usage, its market share slipped to 9.1% as overall industry growth outpaced its expansion. SK On experienced a more significant challenge, with installations falling 7.9% year-on-year to 12.3 GWh, reducing its market share from 4.3% to 3.5%. The decline was primarily linked to slower EV demand among key customers in North America and Europe.

Japan's Panasonic ranked seventh globally with battery installations of 12.0 GWh. The company experienced a 3.7% decline compared with the previous year, resulting in a market share decrease from 4.0% to 3.4%. Slower sales growth from major customer Tesla in several regions contributed to the weaker performance. These developments illustrate the increasing competitive pressure faced by established Japanese and South Korean suppliers as Chinese manufacturers continue expanding their global presence.

Top 10 Rankings Highlight Chinese Market Strength

Further down the rankings, Eve Energy, Svolt Energy, and Sunwoda occupied the eighth, ninth, and tenth positions globally. Their battery installations reached 11.5 GWh, 9.3 GWh, and 8.7 GWh, respectively. The companies achieved year-on-year growth rates of 30.3%, 37.2%, and 17.6%, demonstrating continued expansion across multiple Chinese battery suppliers. Collectively, seven Chinese companies featured within the global top 10 rankings.

The combined market share of these seven Chinese manufacturers reached 72.2% during the January-April 2026 period. This represented an increase of 2.1 percentage points compared with the previous year and further reduced the market presence available to competing Japanese and South Korean battery suppliers. The data underscores the accelerating concentration of global EV battery production and deployment among leading Chinese manufacturers.
