<p>A lithium ion battery that includes: (a) a cathode; (b) an anode in the form of a thin film which, when lithiated, does not exhibit sustained self-heating at temperatures up to about 100 °C; and (c) an electrolyte separating the anode and the cathode. The anode may comprise an electrochemically active elemental metal such as Al, Si, Sn, Sb, Pb, Ge, Mg, Zn, Cd, Bi and In or a mixture thereof. The battery has a capacity of at least 600 milliamp-hours, a specific energy of at least 100 watt-hours/kg, and a volumetric energy of at least 250 watt-hours/liter.</p> |
