BYD to Launch First Solid-State Battery Car in 2027
BYD plans its first solid-state battery vehicle in 2027, with mass production around 2030. The automaker is developing sulfide cells for high-end models.
BYD will release its first car equipped with a solid-state battery in 2027, Executive Vice President Stella Li said. Li added that the company holds a leading position in both the commercialization and technology of solid-state batteries.
The timeline aligns with earlier comments from FinDreams CTO Sun Huajun, who said in February 2025 that BYD would demonstrate and install solid-state batteries in 2027, with mass production expected around 2030. FinDreams is BYD's battery subsidiary.
BYD is developing sulfide solid-state batteries. Chief Scientist Lian Yubo said the technology will mainly be used in high-end models, alongside lithium iron phosphate batteries.
Solid-state batteries replace liquid electrolytes with solid electrolytes made from oxides, polymers or sulfides. They offer higher energy density and are theoretically safer and less prone to catching fire. Cost remains the main problem with current solid-state technology.
Other automakers are pursuing similar timelines. Toyota has committed to offering cars with solid-state batteries by 2027 or 2028. Mercedes-Benz tested a solid-state EQS model and plans to ship the technology before the end of the decade. Stellantis began road testing a solid-state Dodge Charger in 2026, and Honda has partnered with QuantumScape to develop solid-state batteries.
