Abstract: The present disclosure provides an anode plate of a lithium-ion battery and application thereof. The anode plate comprises a current collector, an anode active material layer, and a specially designed lithium-precipitation inhibiting layer. The anode plate of the present disclosure can effectively avoid the lithium precipitation on a surface of the anode plate in an economical and simple way, and meanwhile effectively reduce a capacity ratio of an anode to a cathode, and improve the initial coulombic efficiency, cycle life, energy density, and safety of the lithium-ion battery.
