摘要：NOVELTY - Cobalt oxide coated modified nickel doping lithium manganate complex material (LiNixMn2-xO4/Co3O4), is new. USE - Used as cobalt oxide coated modified nickel doping lithium manganate complex material. ADVANTAGE - The material has good cycle stability and rate performance and high temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for cobalt oxide coated modified nickel doping lithium manganate complex material comprising: (i) preparing nickel-doped lithium manganate by mixing of lithium hydroxide hydrate, nickel acetate tetrahydrate, manganese acetate tetrahydrate and citric acid, adding deionized water, stirring for half an hour, transferring into oil bath, heating to 80 degrees C, adjusting pH to 7.5 to obtain the brown oily gel, drying of microcapsules by microwave to obtain white dry gel, grinding of dry gels into powder, placing in a tube furnace at 5 degrees C with air atmosphere for 10 hours to obtain a nickel-doped lithium manganate material and (ii) mixing of nickel-doped lithium manganate material with cobalt acetate tetrahydrate, grinding, adding absolute ethanol for 30 minutes, drying in an oven at 80 degrees C for 12 hours, placing the resulting powder in a tube furnace, incubating at 400 degrees C for 3 hours in an air atmosphere at a heating rate of 5 degrees C/minute to obtain product.
