A stable lithium sulfide membrane is constructed in situ to wrap the mixed sulfur/C material surface of a lithium–sulfur battery (LSB) by delicately tuning the galvanostatic discharge current. The membrane offers unique and selective channels which allow only ions/small sulfides to pass through and...
