Inverse spinel compounds as cathodes for lithium batteries

摘要

High voltage lithium batteries can be made using lithium transition metal oxides having an inverse spinel structure as a cathode material wherein lithium atoms occupy up to half of the 16d sites, oxygen atoms occupy the 32e sites, and transition metal atoms occupy the 8a sites and about half of the 16d sites in said inverse spinel structure. In particular, these inverse spinel compounds can be suitable for use in lithium ion batteries. Along with high operating voltage, such batteries can exhibit reasonable capacity, great capability and reversibility.
