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.
L'invention concerne une batterie ion-lithium comprenant: (a) une cathode; (b) une anode se présentant sous la forme d'une couche mince qui, lorsqu'elle est lithiée, ne présente pas d'auto-chauffage prolongé à des températures allant jusqu'à environ 100 ·C; (c) un électrolyte séparant l'anode et la cathode. L'anode peut contenir un métal élémentaire à activité électrochimique tel que Al, Si, Sn, Sb, Pb, Ge, Mg, Zn, Cd, Bi et In ou bien un mélange de ceux-ci. La batterie a une capacité d'au moins 600 milliampères-heure, une énergie spécifique d'au moins 100 watts-heure/kg, et une énergie volumétrique d'au moins 250 watts-heure/litre.
