Transition-metals doped lithium-rich anti-perovskites for cathode applications

Abstract

Transition-metal doped Li-rich anti-perovskite cathode compositions are provided herein. The Li-rich anti-perovskite cathode compositions have a chemical formula of Li(3-δ)M5/mBA, wherein 0<δ<3m/(m+1) and δ=3m/(m+1) is the maximum value for the transition metals doping, a chemical formula of Li4-δMsδ/mPC4A, wherein 0<δ≦4m/(m+1) and δ=4m/(m+1) is the maximum value for the transition metals doping, or a combination thereof, wherein M is a transition metal, B is a divalent anion, and A is a monovalent anion. Also provided herein, are methods of making the Li-rich anti-perovskite cathode compositions, and uses of the Li-rich anti-perovskite cathode compositions.
