Global EV Battery Market Growth 2025: SNE Research Data Highlights

On February 4, SNE Research released its monthly power battery statistics covering global electric vehicles, including BEV, PHEV, and HEV models, sold in December 2025. The data confirms that global EV battery market growth remained strong throughout the year, supported by steady electrification momentum across major automotive regions.
From January to December 2025, worldwide battery installations climbed 31.7% year-on-year to reach 1,187 GWh. This expansion reflects sustained EV adoption, even as automakers and suppliers adjusted strategies amid pricing pressure, regional policy shifts, and changing consumer demand patterns.

Supplier landscape and regional concentration

An analysis of the top 10 battery suppliers by national origin shows Chinese manufacturers accounting for 70.4% of total installations in 2025. South Korean suppliers followed with a 15.3% share, while Japanese manufacturers held 3.7%, highlighting the continued concentration of capacity and scale advantages in China.

Top battery suppliers performance in 2025

Among individual companies, the top five suppliers recorded notable growth, although performance gaps widened significantly during the year. The leading suppliers were:

• CATL, which increased installations by 35.7% year-on-year to 464.7 GWh, securing a 39.2% market share

• BYD, with volumes rising 27.7% to 194.8 GWh, accounting for 16.4% share

• LG Energy Solution, posting 108.8 GWh, up 11.3%, with a 9.2% share

• CALB, achieving 62.8 GWh, reflecting 52.6% growth and a 5.3% share

• Gotion, expanding rapidly to 53.5 GWh, an 82.5% increase, capturing 4.5% share

SNE Research assessed 2025 as a year when performance volatility among battery manufacturers widened, despite continued global EV demand growth. Diverging regional market conditions and intensifying competition played a central role in shaping outcomes across suppliers.

Regional market dynamics and strategic implications

In China, sustained pressure to reduce battery cell prices persisted throughout the year, driven by the strengthening cost competitiveness of LFP-focused solutions. This environment favored large-scale domestic players while compressing margins across the supply chain.
In Europe, the rising market share of Chinese battery manufacturers constrained profitability recovery for South Korean suppliers. Increased competition limited pricing power, even as demand for electrified vehicles continued to expand across key European markets.
In North America, growing uncertainty around EV demand prompted major automakers to begin full-scale adjustments to their electrification strategies. These shifts slowed the recovery of utilization rates and shipment volumes for Korean battery manufacturers, resulting in a slower-than-expected rebound compared with other regions.
