Abstract

An electrode for a lithium battery that includes (a) an electrochemically active metal element which, prior to cycling, is in the form of an intermetallic compound or an elemental metal and (b) a non-electrochemically active metal element. The electrode have high initial capacities that are retained even after repeated cycling. The electrode also exhibit high coulombic efficiencies.
