Abstract
A lithium-ion battery anode material containing surface-coated disordered rocksalt lithium vanadium oxide is disclosed. The surface coating contains a species selected from the group consisting of carbon, a metal oxide, a metalloid oxide, a metal fluoride, a metalloid fluoride, a metal phosphate, a metalloid phosphate, and combinations thereof. Materials, designs, synthesis methods, and devices related to fast-charging lithium-ion batteries are provided. This invention fills a technology gap by providing anode materials with disordered rocksalt lithium vanadium oxides to achieve fast charging in 10 minutes or less, greater than 200 W·h/kg energy density, a lifetime of at least 10,000 cycles, and improved battery safety. Methods of making and using the optionally surface-coated disordered rocksalt lithium vanadium oxide are disclosed. Many experimental examples are included, demonstrating several remarkable attributes of this battery technology.
