NOVELTY - A lithium ion superimposed core comprises one or more positive plates and one or more negative plates arranged in a staggered stack. At least one of the positive plates is located on the outermost layer of the superimposed core. The positive plates located in the outermost layer of the superimposed core comprise a positive electrode current collector, a positive electrode active layer and a lithium supplement layer. The positive electrode active layer is arranged on the surface of the positive electrode current collector close to the inside of the laminated core. The lithium supplement layer is arranged on the other surface of the positive electrode current collector away from the inside of the laminated core. The lithium supplementation layer comprises a lithium-rich compound. USE - Lithium ion superimposed core for lithium ion battery (claimed). ADVANTAGE - The lithium ion superimposed core does not leave non-active material or air hole in the anode active layer, which can effectively improve the electrochemical performance of the lithium ion battery.
