Battery current collector cleaning device and method

Abstract

The invention discloses a battery current collector cleaning device and method, and particularly relates to the technical field of current collector cleaning. The battery current collector cleaning device comprises a cleaning pool. A cleaning mechanism is arranged in the cleaning pool. An air-drying mechanism is arranged on one side of the cleaning pool. The cleaning mechanism comprises a first supporting plate which is fixedly arranged on one side of the cleaning pool. Two vertical plates are fixedly arranged on the top of the first supporting plate. A first rotary roller is arranged betweenthe two vertical plates. The two ends of the first rotary roller are connected with the two vertical plates through bearings correspondingly. A plurality of conveying assemblies are arranged on the cleaning pool. The cleaning pool is filled with cleaning liquid. By designing the cleaning mechanism, a current collector can be cleaned, oxidization of surfaces of positive and negative electrode pieces can be reduced, the adhesive force of slurry on positive and negative electrodes can be increased, meanwhile the adhesion quantity of the slurry on the positive and negative electrodes can be increased, the battery capacity is improved, and meanwhile the current collector is cleaned by ultrasonic waves emitted by an ultrasonic generator.

Description

technical field [0001] The invention relates to the technical field of collector cleaning, in particular to a battery collector cleaning device and a cleaning method thereof. Background technique [0002] Battery current collector, as the name implies, refers to the structure or parts that collect current. In lithium-ion batteries, it mainly refers to metal foil, such as copper foil and aluminum foil. The currents are pooled to form a larger current output, so the current collector should be in full contact with the active material, and the internal resistance should be as small as possible. [0003] The prior art has the following deficiencies: battery current collectors are widely used, but the materials of battery current collectors need to be cleaned before use, so as to make them more conductive. The effect is not very good, which affects the conductive effect of the current collector and is not convenient for users to use. [0004] Therefore, it is necessary to inven...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the embodiment of the present invention provides a battery current collector cleaning device and its cleaning method. The present invention can clean the current collector through the design of the cleaning mechanism, reduce the surface oxidation of the positive and negative electrodes, and increase the amount of positive and negative electrode slurry. At the same time, it can increase the adhesion of the positive and negative electrode slurry and increase the battery capacity. At the same time, the ultrasonic wave is emitted by the ultrasonic generator to clean the current collector, so as to solve the problem that the cleaning effect of the cleaning device in the prior art is not good. Very good, it affects the conductive effect of the current collector and is not convenient for users to use
