China’s Changan Automobile is making bold moves in the electric vehicle world. At a recent investor event, the company revealed that it plans to launch prototype EVs powered by solid-state batteries as early as late 2025. With testing and validation expected through 2026, Changan wants to begin mass production by 2027. If successful, this could position them as one of the first automakers to bring next-gen battery tech to the streets on a large scale.
What Makes Solid-State Batteries So Revolutionary?
Solid-state batteries are being developed to overcome the limitations of traditional lithium-ion packs. Unlike conventional batteries that use a liquid electrolyte, solid-state versions rely on a solid electrolyte, making them more stable, more compact, and potentially more powerful. Changan claims its version could deliver a stunning 1,500 kilometers of range on a single charge, far more than most EVs offer today.
This leap is possible thanks to the significantly higher energy density of solid-state technology. While today’s EV batteries max out around 400 Wh/kg in theory (and closer to 230 Wh/kg in real-world use), solid-state batteries could reach up to 500 Wh/kg. That means smaller, lighter batteries that pack more energy and can charge faster. They also promise improved safety by reducing the fire risk associated with liquid electrolytes.
Who Else Is Racing Toward This Tech?
Changan is not the only company chasing this breakthrough. Industry giants like BYD and CATL are also eyeing small-batch production of solid-state batteries by 2027. CATL, the world’s leading EV battery producer, made similar announcements last year, suggesting the entire Chinese auto sector sees this as the next big frontier.
If these timelines hold, we might see the first wave of production EVs with solid-state batteries before the decade ends. Still, mass-market adoption could take until 2030 or beyond. That gives Changan a few short years to turn its vision into reality and take a leading role in a battery revolution that could reshape the future of electric mobility.
