LiMPO4-BASED COMPOSITIONS OF MATTER FOR CATHODES FOR HIGH-PERFORMANCE Li BATTERIES

摘要

A LiMPO4-based composition of matter suitable for use to form cathodes to form high-performance Li-based batteries is disclosed. The composition of matter is defined by the formula LiMPO4, where M is at least one transition metal, and wherein the composition of matter has a general lattice structure. The composition of matter includes Ru ions that substitute for at least one of Li ions and at least one of the ions of the at least one transition metal M. Methods of forming the composition of matter are also disclosed.
