LITHIUM ION BATTERIES INCLUDING STABILIZED LITHIUM COMPOSITE PARTICLES

摘要

A lithium ion battery having a cathode and an anode, the cathode includes a material having an olivine or spinel structure, the anode includes a coating of a composite lithium powder coated with a complex lithium salt, such as LiPF6, LiBF4, LiClO4, LiAsF6, LiF3SO3, and mixtures thereof. A separator is disposed between the anode and the cathode, and a non-aqueous electrolyte solution in contact with the cathode, the anode, and the separator. The anode can include a carbon material. A layer of a composite lithium powder coated with a complex lithium salt can be disposed between the anode and the separator.
