Abstract
Lithium ion battery positive electrode material are described that comprise an active composition comprising lithium metal oxide coated with an inorganic coating composition wherein the coating composition comprises a metal chloride, metal bromide, metal iodide, or combinations thereof. Desirable performance is observed for these coated materials. In particular, the non-fluoride metal halide coatings are useful for stabilizing lithium rich metal oxides.
