BYD Claims Leading Position in Solid-State Battery Development with First EV Launch Planned for 2027

During an exclusive interview, BYD executive vice president Stella Li confirmed the company's accelerating progress in solid-state battery development across both technological innovation and commercialization. She stated BYD will demonstrate its leading position by launching its first model equipped with solid-state battery technology in 2027.

Li emphasized that BYD's research and development team is "very strong," focusing on comprehensive work encompassing not only battery chemistry but also manufacturing processes and equipment required for mass production. She noted that virtually any battery technology under investigation by the industry can be found somewhere within BYD's R&D operations.

BYD's battery subsidiary FinDreams plans to begin limited production of sulfide-based all-solid-state batteries in 2027, scaling toward mass production by 2030. Sulfide electrolytes offer improved stability and longevity compared to traditional lithium-ion batteries, enabling faster charging and extended driving range. BYD's premium brands, including Denza and Yangwang, are positioned to debut the technology first before it becomes available across the company's broader vehicle portfolio.
