View the Complete Application at the US Patent & Trademark Office
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.sub.(3-.delta.)M5/.sub.mBA, wherein 0<.delta.<3m/(m+1) and .delta.=3m/(m+1) is the maximum value for the transition metals doping, a chemical formula of Li.sub.4-.delta.Ms.sub..delta./mPC.sub.4A, wherein 0<.delta..ltoreq.4m/(m+1) and .delta.=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.
