Changan Automobile has announced its plans to integrate all-solid-state batteries into prototype vehicles by the end of 2025. This move underscores the company’s commitment to advancing next-generation battery technology within the electric vehicle (EV) sector. The Jinzhongzhao all-solid-state batteries developed by Changan are expected to be featured in functional prototype vehicles later this year.
During a recent investor communications conference, Changan emphasized its dedication to providing energy independence for its customers by accelerating the development of next-generation batteries. The company aims to validate the performance of solid-state batteries in vehicles by 2026 and intends to begin mass production by 2027.
Changan’s all-solid-state batteries are projected to achieve an energy density of up to 400 Wh/kg, which would allow electric vehicles to exceed a range of 1,500 kilometers on a single charge. This significant range improvement aims to reduce range anxiety among EV users. Additionally, the company has enhanced battery safety by 70% through the implementation of AI-driven remote diagnostic technology, addressing the safety issues commonly associated with liquid electrolyte batteries.
The initiative to mass-produce all-solid-state batteries aligns with similar efforts from other domestic automakers and battery manufacturers.
In April 2024, Wu Kai, chief scientist at Contemporary Amperex Technology Co. Limited (CATL), stated at a recent battery industry event that CATL plans to begin small-scale production of all-solid-state batteries by 2027.
While traditional liquid lithium batteries can achieve energy densities of around 350 Wh/kg, further increases are becoming challenging. In contrast, all-solid-state batteries are expected to reach energy densities of up to 500 Wh/kg. Despite these promising advancements, industry experts like Sun Huajun, battery business CTO at BYD, suggest that widespread adoption of solid-state batteries may not occur until after 2030.
Changan reiterated its commitment to the development and production of all-solid-state batteries during an event last month, reaffirming its goal to commence mass production by 2027. This strategic move positions Changan alongside other leading companies striving to innovate and enhance the performance and safety of EV batteries.
