The automotive industry is rapidly advancing toward the commercialization of all-solid-state batteries, with major Chinese manufacturers targeting 2027 for mass production. Companies including BYD, SAIC Motor, Changan Automobile, Chery, and Dongfeng are currently testing prototypes that promise significantly higher energy densities, faster charging capabilities, and improved safety compared to traditional liquid lithium-ion batteries. While technical hurdles remain, these firms are betting on this next-generation technology to extend driving ranges beyond 1,000 kilometers. Industry leaders emphasize that these batteries will complement existing liquid and sodium-ion technologies to accelerate the global transition to electric propulsion.
BYD, which recently introduced its Blade Battery 2.0, plans to initiate limited production of sulfide-based all-solid-state batteries by 2027, with full-scale manufacturing expected by 2030. According to the company, sulfide electrolytes offer superior stability and longevity. These advanced power units are slated to debut in high-end sub-brands like Denza and Yangwang before eventually reaching mass-market vehicles. BYD’s leadership maintains that while solid-state technology is a critical development, it should not be viewed as a total replacement for current battery types, but rather as a strategic addition to the broader electric vehicle ecosystem.
Other major players are moving at a similar pace. SAIC Motor, having already launched a semi-solid-state vehicle, is working toward a 2027 rollout for its all-solid-state technology, which boasts an energy density exceeding 400 Wh/kg. Similarly, Changan Automobile and Chery have reported development of batteries capable of delivering ranges over 1,500 kilometers. These advancements are not limited to China; international efforts include Mercedes-Benz testing solid-state cells from the U.S.-based startup Factorial Energy. By replacing liquid electrolytes with solid materials, manufacturers aim to eliminate combustion risks while achieving the efficiency required to dominate the future electric vehicle market.
