Changan will aim to mass-produce solid-state batteries from 2027

Chinese state-owned Changan Automobile plans to put solid-state batteries in prototype cars by the end of 2025, early 2026. The aim is to validate solid-state vehicle batteries by the end of 2026 and begin mass production by 2027.

Changan announced its commitment to accelerating the progress of new-gen battery technology during an investor conference.

BYD and CATL are also planning on producing solid-state batteries in small batches by 2027.

Solid-state batteries are a new technology that has been developed to replace liquid lithium batteries. They can achieve a higher energy density (of up to 500 Wh per kg) and thus can provide more range and faster charging. They're also safer to charge and aim to solve the safety hazards of liquid batteries. Changan says you could hope for some 932 miles of range from a solid-state battery EV!

The current-gen car batteries have a theoretical energy density of up to 400 Wh per kg (but realistically are lower - the VW ID.4's battery is around 230 Wh per kg).

Last year, CATL, the world's leader in battery production, revealed its aim to produce all-solid-state batteries in small batches by 2027. Changan shared the same ambitious timeline.

We could expect large-scale adoption of solid-state batteries in EVs around 2030 if current projections pan out.
