Abstract

Abstract: The densification process of electrical paste particles during the process of battery pole piece rolling is studied. The mechanism of the pole rolling is analyzed theoretical;the basic parameters of the electric slurry particles in the movement are described; the force equation is established; and the basic conditions for the stable rolling are analyzed. The dynamic simulation is carried out by using relevant parameters, and the results are verified by theoretical analysis, numerical simulation and experimental verification. The results show that there is a certain relationship between the relative density of the electrode paste and the thickness of the electrode. The study verified the densification of the electric slurry particles during the whole rolling process. Theinfluence of the density uniformity and thickness uniformity on the battery quality was also investigated, which provided guidance for the battery production.
