BYD Says Its First Solid-State EV Arrives Next Year

Solid-state batteries have long been billed as the next major step forward for electric vehicles, promising less weight, better safety, higher energy density and quicker top-ups. The catch has always been manufacturing: nobody has managed to build them at scale yet. BYD now claims it is closer than most.

Executive vice president Stella Li said the company holds a leading position in the technology and intends to prove it by putting solid-state cells into one model next year. She did not name the vehicle or give a launch date, and it remains unclear whether this will be a show car or something buyers can actually order. Given how fast BYD tends to move from concept to showroom, a production car is a real possibility.

Reports from China suggest the technology could debut in the Yangwang flagship sedan that BYD previewed in camouflage recently — a very large, very opulent machine. Flagship models have always been where expensive new tech appears first, so a premium badge like Yangwang, Denza or the Great Tang line would be a logical starting point.

Rivals are not standing still. Toyota is targeting a solid-state EV around 2027 or 2028, Honda and Mercedes point to roughly 2030, and Hyundai continues its own work on the chemistry. For American buyers, though, the practical question is when a non-Chinese brand will bring the technology to their market.
