Chinese automakers are rapidly advancing solid-state battery technology, promising EVs that are both safer and capable of greater ranges. This new solid-state approach is seen as a superior alternative to current liquid lithium-ion batteries.

Chinese electric vehicle (EV) batteries are set to become safer and more powerful, as carmakers including SAIC Motor and Chery Automobile outline road maps for the commercialisation of solid-state technology. Solid-state batteries – which use a solid electrolyte to conduct ions between electrodes – are widely seen as a superior alternative to conventional lithium-ion batteries that rely on liquid or gel-based materials. Analysts say the technology promises higher energy density, improved safety....
