CATL Remains the Clear Global Leader

CATL continued to dominate the global EV battery market in 2025 with 464.7 GWh of battery installations and a 39.2% market share. It remains the only battery supplier with a share comfortably above 30%, underlining its unmatched scale and customer base.

CATL’s strength comes from its strong presence across China, Europe and global EV platforms. Its customer base includes several major automakers, while its leadership in LFP and advanced battery technologies has helped it remain ahead of both Korean and Japanese rivals.

BYD Strengthens Its No. 2 Position

BYD ranked second globally with 194.8 GWh of installations and a 16.4% market share in 2025. BYD’s advantage is different from CATL’s because it is not just a battery manufacturer but also one of the world’s largest EV makers. This vertical integration helps BYD control costs, secure supply and rapidly scale EV production.

Together, CATL and BYD accounted for 659.5 GWh of battery installations, equal to 55.6% of the global EV battery market in 2025.

China Dominates the Top 10

Six of the top 10 EV battery manufacturers in 2025 were Chinese companies: CATL, BYD, CALB, Gotion High-Tech, EVE Energy and Svolt. This highlights China’s control over the EV battery value chain, from raw-material processing and cell manufacturing to EV production and exports.

The Chinese advantage is built on scale, lower cost structures, strong domestic EV demand and rapid adoption of LFP chemistry. LFP batteries are particularly important because they are cheaper, safer and increasingly preferred for mass-market EVs.

South Korean and Japanese Players Still Matter

LG Energy Solution remained the top non-Chinese EV battery manufacturer in 2025, with 108.8 GWh of installations and a 9.2% global market share. SK On and Samsung SDI also remained in the top 10, while Panasonic continued to be Japan’s key global battery player.

However, Korean and Japanese companies are under pressure as Chinese battery makers continue to expand faster and offer more cost-competitive solutions.

Top Electric Vehicle Battery Manufacturers in India

India is not yet a global-scale EV battery cell manufacturing hub like China, South Korea or Japan. Most EV batteries used in India still depend heavily on imported cells, mainly from China, South Korea and other Asian suppliers. However, this is now changing as Indian companies and global partners invest in local lithium-ion cell manufacturing.

India’s push is being supported by the Production Linked Incentive scheme for Advanced Chemistry Cell battery storage, under which the government selected companies including Reliance New Energy Solar, Ola Electric Mobility, Hyundai Global Motors and Rajesh Exports for incentives under the ₹18,100 crore programme.

India’s EV Battery Market: Still Early, But Strategically Important

India’s EV battery industry is at a much earlier stage compared with China. The biggest gap is in cell manufacturing. Many Indian players currently assemble battery packs, but the real value and strategic control sit in the manufacturing of battery cells.

This is why companies such as Tata Agratas, Ola, Reliance, Exide and Amara Raja are important. They represent India’s move from battery pack assembly to deeper cell localisation.

Auto Punditz Takeaway

The global EV battery market is currently dominated by China, with CATL and BYD far ahead of the rest. South Korean and Japanese companies remain important, but their global share is under pressure.

India, meanwhile, is still in the early phase of EV battery cell manufacturing. The country does not yet have a CATL- or BYD-scale battery company, but the direction is clear. Tata Agratas, Ola, Reliance New Energy, Exide Energy Solutions and Amara Raja could become the key pillars of India’s battery localisation story over the next decade.

For Indian EV buyers, local battery manufacturing could eventually mean better pricing, more stable supply, improved localisation and faster EV adoption.
