NOVELTY - Preparing uniform and controllable pre-lithiated anode sheets, includes immersing the second-pass rolled anode sheets with a lithiation coating into molten liquid lithium in an inert environment, and performing surface extrusion and a third solidification. USE - Method for uniform and controllable preparation of pre-lithium pole piece used in lithium ion battery used in electric automobile, consumer electronics field and energy storage field. ADVANTAGE - The method can make the molten metal lithium embedded in the electrophilic coating lithium the pole piece by controlling the thickness of the lithium coating, coating the solid content of the slurry, the pressure of the second rolling pressure and soaking time, realizing accurate control of lithium amount. The method is easier to realize the uniform and accurate control the pre-lithium, and is good for improving the first ring discharge capacity of the battery, so as to improve the energy density lithium the ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a prelithium pole piece. (Drawing includes non-English language text).
