NOVELTY - Three-dimensional spherical nickel-cobalt-molybdenum-oxide (NiCoMo-O) composite electrode material synthesized by one-step hydrothermal method and high temperature calcination, and NiCoMo-O graphe oxide (rGO) composite electrode material synthesized by an electrostatic assembly method, are new. USE - Three-dimensional spherical NiCoMo-O composite material is used for cathode material of secondary lithium battery (claimed) used in household appliances and portable electronic device, and energy electric automobile and energy storage power station. ADVANTAGE - The three-dimensional spherical nickel-copper-molybdenum-oxide composite material has excellent electrochemical performance, and reduces the ion diffusion length, and effectively adapts the volume expansion, and enhances the conductivity/ionic conductivity and mechanical stability of the cathode material of the lithium ion battery.
