Elastic and Li-ion-percolating hybrid membrane stabilizes Li metal plating.

ABSTRACT: Lithium metal batteries are capable of revolutionizing the battery marketplace for electrical vehicles, owing to the high capacity and low voltage offered by Li metal. Current exploitation of Li metal electrodes, however, is plagued by their exhaustive parasitic reactions with liquid electrolytes and dendritic growth, which pose concerns to both cell performance and safety. We demonstrate that a hybrid membrane, both elastic and Li⁺-ion percolating, can stabilize Li plating/stripping with high Coulombic efficiency. The compact packing of a Li⁺ solid electrolyte phase offers percolated Li⁺-conducting channels and the consequent infiltration of an elastic polymer endows membrane flexibility to accommodate volume changes. The protected electrode allows Li plat
