Chinese scientists have developed a new battery system that could enable lithium cells to operate safely for thousands of hours, an advance that could lead to better batteries for electric vehicles and power grids.

Lithium metal batteries have become the cornerstone for future power systems due to their high energy storage capacity.

However, the current liquid electrolytes in these cells pose several risks, including leakage and combustion, and the growth of lithium metal inside batteries into needle-like or branch-like structures during charging, which compromises battery safety and performance .

Emerging studies suggest new types of electrolytes called deep eutectic gel electrolytes (DEGEs) can help overcome these issues due to their high charge conduction capacity and inherent
