NOVELTY - Pre-lithium negative electrode sheet comprises a negative electrode current collector, a negative electrode material layer arranged on one side of the negative electrode current collector, and a pre-lithiated layer arranged on the other side of the negative electrode current collector. USE - The pre-lithium negative electrode sheet is useful for laminated batteries, and forming lithium negative electrode, pre-lithium battery cell, wound-type batteries, and lithium-ion battery. ADVANTAGE - The pre-lithium negative electrode sheet can effectively compensate the irreversible active loss lithium the charging and discharging process, does not need prolonged time high temperature standing, and has high pre-lithium efficiency, and improves the first coulomb efficiency and cycle performance of the ion battery lithium. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A method for preparing a lithium negative electrode, involving (a) using a dry electrode preparation process, setting the negative electrode material layer on one side of the negative electrode current collector to obtain a single-sided negative electrode sheet, and (b) coating a conductive glue solution on the other surface of the negative electrode current collector to form a conductive glue layer, and setting a lithium source on the conductive glue layer to obtain the electrode sheet. A pre-lithium battery cell comprising the electrode sheet, two-electrode composite unit stacked repeatedly, where the positive electrode sheet and electrode sheet are separated by a diaphragm between adjacent electrode sheets, and the two-electrode composite unit comprises a positive electrode sheet and a negative electrode sheet stacked in sequence, and the pre-lithiated layer is located on the side of the negative electrode current collector away from the repeatedly stacked two-electrode composite unit. A lithium-ion battery obtained from the pre-lithium battery cell through the formation and volume separation.
