Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.
In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.
Chinese Dominance
Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.
The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and various Li Auto models.
| Company | Country | 2023 Production (megawatt-hour) | Share of Total Production |
|---|---|---|---|
| CATL |  China | 242,700 | 34% |
| BYD | China | 115,917 | 16% |
| LG Energy Solution |  Korea | 108,487 | 15% |
| Panasonic |  Japan | 56,560 | 8% |
| SK On | Korea | 40,711 | 6% |
| Samsung SDI | Korea | 35,703 | 5% |
| CALB | China | 23,493 | 3% |
| Farasis Energy | China | 16,527 | 2% |
| Envision AESC | China | 8,342 | 1% |
| Sunwoda | China | 6,979 | 1% |
| Other | – | 56,040 | 8% |
In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.
The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.
Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.
Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.
