Chinese scientists say they have developed a solid-state lithium battery that can match the performance of other candidates for next-generation battery technology at less than 10 per cent of the cost.

The move puts China a step closer to its ambition to be first to deliver what many regard as the future of rechargeable battery technology, with its potential to revolutionise the electric vehicle industry.

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.
