According to CnEVPost, Chinese automaker Changan claims it has developed a solid-state battery that will allow electric cars to travel up to 1500 kilometers without needing to be recharged. That’s a massive 932 miles.
Changan says its batteries will be in production by the end of this year, with verification and calibration procedures taking place next year. By 2027, it expects production cars using its solid-state batteries to be on the road in China.
The Changan solid-state battery is said to have an energy density of up to 400 Wh/kg compared to the best lithium-ion batteries which have an energy density of 350 Wh/kg, but they are expensive. Once fully developed, solid-state batteries are expected to be capable of energy densities as high as 500 Wh/kg

PSR Analysis: On the face of things, this is great news because it also eliminates the risk of thermal runaway. However, we must remember that the detail is important and if this uses the CLTC method of calculating range (rather than the WLTP method) it could be more hype than substance. PSR
