Global EV Battery Market Grows 19.7% Through August

Global EV Battery Installations Continue Rising

The global EV battery market continued expanding through the first eight months of 2026, according to monthly data announced by SNE Research on October 2. Global battery installations for electric vehicles, including BEVs, PHEVs and HEVs, reached 844.2 GWh from January through August, representing a 19.7% increase from the same period a year earlier. The growth shows that battery demand remains on an upward trajectory globally, although the pace of expansion varies significantly by region. The data also highlights the increasingly important role of Chinese manufacturers, which accounted for 73.2% of the market among the top 10 suppliers during the period.

Chinese Suppliers Maintain Strong Market Position

Chinese battery manufacturers continued to dominate the supplier rankings during January-August 2026. Among the top 10 suppliers, Chinese companies held a 73.2% share, compared with 11.0% for Korean manufacturers and 3.5% for Japanese manufacturers. CATL remained the leading supplier, with installations rising 25.2% year over year to 333.0 GWh and giving the company a 39.4% market share. BYD ranked second after increasing installations 6.2% to 127.9 GWh, equivalent to a 15.1% share. The concentration of supply underscores the strong competitive position of Chinese battery producers.

Top Five Battery Suppliers Post Double-Digit Growth

The leading supplier group also included LG Energy Solution, CALB and Gotion. LG Energy Solution increased its installations 0.9% year over year to 68.3 GWh, representing an 8.1% share of the global market. CALB recorded stronger growth of 32.6%, reaching 44.4 GWh and a 5.3% share, while Gotion grew 47.1% to 41.5 GWh and captured 4.9% of the market. The performance of these suppliers shows that growth is not evenly distributed across the leading manufacturers, with several Chinese companies expanding substantially faster than some established competitors during the January-August period.

Regional Battery Demand Shows Wider Divergence

SNE Research said the global market maintained growth of around 20% during January-August 2026, but regional differences became more pronounced. China increased 16.9% to 483.7 GWh, while Europe grew 29.2%. Asia excluding China recorded much faster growth of 76.0%, and South America increased 179.9%. In contrast, North America declined 23.7% to 73.1 GWh. The regional split indicates that battery demand is developing at very different rates across major markets, creating different operating conditions for battery manufacturers and influencing where companies may prioritize production capacity and investment.

U.S. Weakness Drives Greater ESS Production

In the United States, EV battery demand has remained weak since the federal EV tax credit ended, according to SNE Research. The weaker market environment is prompting battery manufacturers to increasingly convert production lines originally intended for EV batteries toward energy storage system production. This shift demonstrates how manufacturers are responding to changing demand conditions by redirecting existing manufacturing capacity toward another battery application. The development is particularly relevant as regional demand patterns continue to diverge, potentially affecting production planning, capacity utilization and the allocation of battery manufacturing resources across markets.

China Changes Battery Tax and Export Policies

China introduced a 2% consumption tax on lithium-ion batteries sold domestically in September and plans to eliminate the export VAT rebate for batteries in January next year. These policy changes could influence the cost structure and pricing strategies of Chinese battery suppliers as the year progresses. SNE Research expects supplier pricing policies and the pace of overseas production expansion to play an important role in shaping competition through the end of 2026. The combination of domestic taxation and changes to export incentives therefore adds another factor for battery companies evaluating pricing, international manufacturing and market expansion strategies.

Industry Impact & Outlook

The latest battery data points to continued global expansion alongside a sharper regional divide, with strong growth in Europe, Asia outside China and South America contrasting with weakness in North America. Chinese suppliers remain particularly influential because of their dominant share among leading manufacturers, while changing Chinese tax and export policies could affect their pricing and overseas production decisions. For automakers and battery producers, the diverging demand environment may encourage greater flexibility in manufacturing allocation and regional capacity planning. The shift from EV battery production toward energy storage in weaker markets also shows how battery manufacturers may increasingly adapt their operations to changing electrification demand.

Frequently Asked Questions

How much did the global EV battery market grow through August 2026?
The global EV battery market increased 19.7% during January-August 2026, reaching 844.2 GWh in battery installations worldwide. The growth covered batteries installed in BEVs, PHEVs and HEVs sold during the period. China remained the largest regional market at 483.7 GWh, while Europe, Asia excluding China and South America recorded stronger percentage growth. North America moved in the opposite direction, declining 23.7% to 73.1 GWh. The data indicates continued overall expansion but increasingly different regional demand conditions across major markets.
