BYD to Implement Solid-State Batteries in Vehicles Starting 2027
BYD Executive Vice President Stella Li, in an interview in Valencia, Spain, has confirmed that the company will begin installing solid-state battery technology in its cars starting next year.
According to a report from Car News China on Sunday (13/9) local time, Li’s statement sets a short-term demonstration target, though it does not establish a specific schedule for retail launch or mass production. Li confidently stated that the company has been exploring various battery technologies for electric vehicles within its research and development centres, including solid-state batteries, which are currently recognised as the most cutting-edge technology available.
“Speaking of solid-state batteries, BYD is at the forefront; we are at the forefront for both commercial lines and technology. To prove this, we will even have one model next year that will be the first to feature this technology,” said Li.
Sun Huajun, Chief Technology Officer of FinDreams—a BYD subsidiary—stated that small-scale trials have been prepared to involve approximately 1,000 vehicles by 2027, with larger commercial production targeted for 2030.
These initial trials are expected to focus on high-end platforms, including Yangwang and Denza, as the additional costs associated with solid-state technology are more easily absorbed in these premium segments.
Beyond independent development, BYD is also developing solid-state battery technology within the framework of China’s All-Solid-State Battery Collaborative Innovation Platform (CASIP). This government-backed initiative involves relevant industry players with an investment value of US$830 million (approximately Rp14.6 trillion).
BYD’s vehicles next year will test whether the sulphide technology developed in its laboratories can function effectively outside of a research environment. However, mass production appears to remain a distant step in the company’s roadmap.
In addition to BYD, the development of solid-state battery technology is being pursued by several other companies. For instance, Toyota has targeted the launch of such batteries in its BEV models for 2027-2028 through a partnership with Idemitsu Kosan, while Samsung SDI has also targeted mass production of solid-state batteries by 2027.
Across all these efforts, the primary challenge in current solid-state battery development remains the transition from pilot-scale development stages to large-scale mass production.
