China scientists’ low-cost solid-state battery could be EV industry breakthrough | South China Morning Post

While there have been significant advances in traditional battery packs, their bulk, weight – and potential fire risk – are out of step with the requirements of lightweight, reliable EVs.

Replacing the liquid electrolytes of conventional lithium batteries with a solid-state alternative could promise faster charging times, better performance and improved safety standards.

But large-scale use of solid-state alternatives to conventional lithium batteries has been hampered by high material and manufacturing costs, sparking a global race for a commercially viable solution.

The researchers, from the University of Science and Technology of China (USTC) in the eastern province of Anhui, have developed a type of solid electrolyte that could hold great promise for commercial applications.
