China’s top battery manufacturers are accelerating their efforts to bring solid-state batteries (SSBs) to market, with several major players aiming for trial production and real-world testing in 2027. Companies including BYD, CATL, Geely, Farasis Energy, CALB, and Gotion High-Tech have all outlined plans to validate SSB technology within the next year.
Major Battery Makers Set 2027 SSB Trial Targets
Farasis Energy, CALB, and Gotion High-Tech have each committed to trial production and real-world road tests of solid-state batteries in 2027. This aligns with recent announcements from BYD and CATL, both of which have confirmed their own SSB development timelines for the same year.
BYD has published six patents related to solid-state batteries and reiterated its commitment to begin trials in 2027. CATL, China’s largest battery manufacturer, has also confirmed its 2027 trial plans to investors. Geely, meanwhile, is targeting trial production and validation of its 500 Wh/kg SSB cells in 2027.
Industry Policy and Company Strategies
China’s State Council established the ‘New Energy Vehicle Industry Development Plan (2021-2035)’ in 2020, which includes a goal to accelerate the development and commercialisation of solid-state batteries. This policy framework has helped shape the strategies of leading battery makers.
CALB, the third-largest battery maker in China, has announced small-scale EV validation plans for 2027 and aims to ramp up SSB production between 2030 and 2032. Gotion High-Tech, backed by Volkswagen, is focusing on developing 350 Wh/kg SSB cells, with road tests planned for 2027 and full commercial production targeted for 2029–2030. Farasis Energy, supported by Mercedes-Benz, is also aiming for full-scale commercial production by 2030.
Emerging Players and Technology Developments
EVE Energy has developed sulfide-based SSB cells with capacities in the ampere-hour range. The company plans to showcase its first-generation cells with a maximum energy density of 350 Wh/kg and 800 Wh/L in 2026, and to introduce second-generation 1000 Wh/L cells in 2028.
Dreame Technology, better known for its consumer electronics, has also entered the SSB field. Dreame claims its ‘Galaxy Crystal’ cells offer a maximum capacity of 60 Ah and an energy density exceeding 450 Wh/kg. The company aims to begin small-scale deliveries in 2026 and move to full commercial production in 2027.
Market Share and Industry Landscape
According to China EV DataTracker, CATL leads the Chinese battery market with a 42.9% share, followed by BYD at 19.5%. CALB, Gotion, and EVE Energy rank third, fourth, and fifth, respectively. The top four battery makers together hold over 75% of the market and are all committed to SSB trial production in 2027.
Smaller players are also pursuing SSB development, viewing it as an opportunity to compete with larger rivals.
Why this matters
The commitment of China’s leading battery manufacturers to trial solid-state batteries in 2027 signals a coordinated push to advance battery technology. SSBs are widely seen as a potential breakthrough for electric vehicles, offering higher energy density and improved safety compared to current lithium-ion cells.
If successful, these efforts could accelerate the adoption of next-generation EVs and reshape the global battery industry.
What this means for buyers
Buyers should watch for announcements from major Chinese automakers and battery suppliers regarding SSB-equipped vehicles in the coming years. While commercial availability is still several years away, the 2027 trial production targets suggest that SSB-powered EVs could reach the market by the end of the decade.
Consumers interested in the latest battery technology may want to monitor developments from BYD, CATL, Geely, and emerging players like Dreame Technology.
