NEGATIVE ELECTRODE PLATE AND PREPARATION METHOD THEREFOR, AND LITHIUM BATTERY

The present application provides a negative electrode plate comprising a substrate, which comprises a current collector and negative electrode active material bonded on the current collector; first lithium bands arranged on a front surface of the substrate; second lithium bands arranged on a back surface of the substrate; the first lithium bands and the second lithium bands are mutually staggered; adjacent ones of the first lithium bands are spaced apart and adjacent ones of the second lithium bands are spaced apart, respectively. The present application greatly improves the diffusion rate of the lithium bands on a contact surface, and reduces the consumption amount of lithium bands, so as to effectively reduce waste of lithium resources, guarantees that the lithium ions are embedded in the electrode to the maximum extent, thereby improving the long-term cyclic performance of the lithium battery, and also reduces the electrode plate weight of the electrode itself, thereby improving the design space for the entire lithium battery.
