Abstract: The present disclosure relates to a lithium ion battery electrode. The lithium ion battery electrode comprises a current collector and at least one electrode material layers stacked on the current collector. Each of the at least one electrode material layers comprises an electrode active material layer, a conductive agent, an adhesive material, and a carbon nanotube layered structure. The conductive agent and the adhesive material are dispersed in the electrode active material layer. The carbon nanotube layered structure is located on the electrode active material layer, and at least part of the carbon nanotube layered structure is embedded in the electrode active material layer. The electrode active material layer is located between the current collector and the carbon nanotube layered structure.
