“…[1][2][3][4] Because Li + intercalation based batteries are gradually approaching their limits of theoreticale nergy density (< 300 Wh kg À1 ), many efforts have been devoted to developing Li metal based ones, such as NCM-Li (NCM = nickel cobalt manganese oxide), [5,6] LiÀS, [3,7] and LiÀO 2 /Li-air.
