TOKYO -- Scientists in China have recharged a solid-state lithium-sulfur battery 1,400 times, a breakthrough that brings the technology closer to commercial reality.

The team of researchers from the Chinese Academy of Sciences was able to maintain roughly 70% of the initial capacity after completing all the charging cycles. The findings were published in the U.S. scientific journal ACS Applied Materials & Interfaces.
