Lithium Supplementing Slurry, Positive Electrode Plate, and Lithium Ion Battery

Abstract

A lithium supplementing slurry, a positive electrode plate, and a lithium ion battery. The lithium supplementing slurry and a positive electrode slurry are separately dispersed and mixed, such that the problems that the positive electrode slurry is difficult to disperse, easy to agglomerate and gel due to direct addition of a lithium supplementing material into the positive electrode slurry are avoided; according to the design of the present disclosure, the lithium supplementing slurry formed by adding the lithium supplementing material, a conductive agent, and a binder may achieve a better dispersion effect; and after the lithium supplementing slurry is coated on a positive electrode coating, the obtained positive electrode plate is lower in impedance and more excellent in lithium supplementing effect. the additive amount of the lithium supplementing material may also be accurately calculated and the residue of the lithium supplementing material after first charging and discharging is effectively reduced.
