Synthesis of disordered rock salt (drx) cathode materials for li-ion batteries

Abstract

A method of making a disordered rock salt cathode material for lithium-ion batteries includes performing combustion synthesis with an aqueous solution of metal-containing compounds. The method may include a two-stage process having a first stage followed by a second stage. The first stage includes performing combustion synthesis to obtain a metal oxide precursor. The second stage includes one or more of lithiating, fluorinating, and annealing the metal oxide precursor to obtain a disordered rock salt (DRX) oxide or oxyfluoride. The obtained disordered rock salt (DRX) may have a chemical composition Li1+xMnyTM1-x-yO2-zFz wherein 0≤x≤0.3, 0.4≤y≤1, 0≤z≤0.3, and TM is one or more transition metals selected from a group of Ti, Zr, Mo, Nb, and V. A lithium-ion battery cathode including a disordered rock salt cathode material and a lithium-ion battery including the lithium-ion battery cathode are also provided.
