The two Chinese giants, CATL and BYD, continue to firmly hold the top two global positions, with a combined market share exceeding 50%.
On October 13, South Korean market research firm SNE Research officially released the “Global Electric Vehicle Battery Usage Report for January-August 2025”.
Data shows that from January to August 2025, global electric vehicle battery usage reached 691.3 GWh, a year-on-year increase of 34.9%.
From the overall perspective of the global electric vehicle battery market, a stable tripartite structure between China, Japan, and South Korea has now formed, with Chinese battery manufacturers showing a continued trend of leading in both growth rate and market scale.
Among the top ten companies in the global power battery installed capacity ranking for January-August, six are Chinese companies: CATL (254.5 GWh), BYD (124.8 GWh), CALB (32.1 GWh), Gotion High-Tech (25.1 GWh), Eve Energy Co., Ltd. (19.9 GWh), and SVOLT (17.5 GWh).
Among them, the two Chinese giants, CATL and BYD, continue to firmly hold the top two global positions, with a combined market share exceeding 50%.
Specifically, CATL maintained the top position with a year-on-year growth rate of 31.9% and an installed capacity of 254.5 GWh; BYD followed closely with rapid growth of 50.3% and an installed capacity of 124.8 GWh; South Korea’s LG Energy Solution ranked third with an installed capacity of 67.4 GWh.
As the leader in the global battery industry, CATL continues to expand its industrial footprint.
CATL’s 2025 interim report shows that the company achieved total revenue of 178.9 billion RMB in the first half of 2025, a year-on-year increase of 7.3%; total R&D investment reached 10.1 billion RMB, a year-on-year increase of 17.5%.
Furthermore, to further break geographical constraints and expand the global production capacity of lithium batteries, CATL’s factory in Indonesia has officially commenced construction, with an annual battery production sufficient to support 200,000 to 300,000 vehicles. Additionally, its factories in Hungary and the joint venture factory with Stellantis in Spain are also steadily progressing.
BYD demonstrates strong growth momentum in the power battery sector.
It is reported that BYD has currently applied for a patent on “solid-state battery electrolyte and its preparation method,” achieving a laboratory energy density of 450 Wh/kg, which is a 50% improvement over its current Blade Battery. Mass demonstration and installation in vehicles are expected to begin in 2027, initially featuring in high-end models such as the Yangwang U9.
