The Chinese company is one of several car makers expected to adopt solid-state batteries in the next few years.

Switching from lithium-ion to solid-state batteries promises to extend the range and charging speeds of electric vehicles, and Chinese car maker BYD believes it's in a "leading position" to commercialize the technology. BYD's Executive Vice President Stella Li shared the claim in a recent interview with Carwow 's Spanish outlet, alongside the news that BYD would release its first car with a solid-state battery in 2027.

Li's comments further confirm plans shared by Sun Huajun, the Chief Technology Officer of BYD's battery subsidiary FinDreams, at a battery conference in February 2025. At the time, Sun said BYD would offer its first demonstration and installation of solid-state batteries in 2027 before the technology enters mass production around 2030, CarNewsChina reports.

For example, Toyota committed to offering cars with solid-state batteries by 2027 or 2028; Mercedes-Benz began testing a solid-state EQS model and shared that it would ship the technology before the end of the decade; and Stellantis began road testing a solid-state Dodge Charger in 2026. Earlier this year, Honda struck up a new partnership with QuantumScape to develop solid-state batteries it hopes will help it reach carbon neutrality by 2050.
