Title: CATION-DISORDERED OXIDES FOR RECHARGEABLE LITHIUM BATTERIES AND OTHER APPLICATIONS
Abstract:
Embodiments related to cation-disordered lithium metal oxide compounds, their methods of manufacture, and use are described. In one embodiment, a cation-disordered lithium metal oxide includes LiaMbM'cO2 with a greater than 1. M includes at least one redox-active species with a first oxidation state n and an oxidation state n' greater than n, and M is chosen such that a lithium-M oxide having a formula LiMO2 forms a cation-disordered rocksalt structure. M' includes at least one charge-compensating species that has an oxidation state y that is greater than n.
