Abstract
A method includes sintering a lithium-rich metal oxide (LRMO) material at a sintering temperature to form a sintered LRMO material and quenching the sintered LRMO material from the sintering temperature to room temperature in less than 500 milliseconds to form a quenched LRMO material represented by a chemical formula Lix(MnyNi1-y)2-xO2, where x is greater than 1.05 and less than 1.25, and y ranges from 0.95 to 0.1.
