- Global EV Battery Installations increased 16.3% during January-May 2026.
- Chinese manufacturers continued strengthening worldwide battery market leadership.
Global EV battery installations continued their upward trajectory during the first five months of 2026, according to data released by SNE Research on July 3. The report, which tracks power battery installations for battery electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV), and hybrid electric vehicles (HEV), showed cumulative installations reached 469.2 GWh between January and May 2026. This represented a 16.3% year-on-year increase, reflecting sustained demand for electrified vehicles across global markets despite evolving competitive and regulatory conditions.
Chinese Manufacturers Strengthen Global Leadership
The latest market figures highlighted the continued dominance of Chinese battery suppliers. Collectively, manufacturers from China accounted for 72.6% of total battery installations among the world's top ten suppliers. Battery makers from South Korea represented 12.1% of the market, while companies based in Japan contributed 3.2%. The distribution illustrates China's strong manufacturing scale and growing influence in the global electric vehicle battery industry.
Top Five Battery Suppliers by January-May 2026 Installations
| Rank | Supplier | 2026 Jan-May (GWh) | 2025 Jan-May (GWh) | Growth Rate | Market Share |
|---|---|---|---|---|---|
| 1 | CATL | 188.4 | 153.3 | 22.9% | 40.2% |
| 2 | BYD | 67.6 | 67.4 | 0.4% | 14.4% |
| 3 | LG Energy Solution | 41.0 | 38.2 | 7.3% | 8.7% |
| 4 | CALB | 23.8 | 17.5 | 36.3% | 5.1% |
| 5 | Gotion | 21.7 | 15.8 | 37.0% | 4.6% |
Market Competition Continues to Evolve
SNE Research stated that competition across the battery industry is becoming increasingly complex. The research organization attributed this trend to broader adoption of lithium iron phosphate (LFP) battery technology, rising demand for energy storage systems (ESS), expanding overseas operations by Chinese manufacturers, and increasingly stringent supply chain regulations across the United States and Europe. These developments are reshaping competitive strategies for global battery suppliers while influencing future investment and production decisions.
Future Competitive Factors
According to SNE Research, future market dynamics will largely depend on how Chinese manufacturers such as CATL and BYD continue leveraging manufacturing scale and cost competitiveness. At the same time, battery suppliers from South Korea and Japan are expected to focus on expanding customer diversification, delivering higher-value battery cells, strengthening ESS portfolios, and increasing localized production capabilities to remain competitive as the global electric vehicle battery market continues to expand.
