Problems solved by technology

[0006] However, in the existing production process, the surface cleaning of the metal foil is basically completed by the metal foil manufacturer, and then transported to the lithium battery production site for use. During this process, due to various reasons, the surface of the metal foil The cleanliness has declined, and the quality of lithium batteries produced directly using this metal foil is unstable. At the same time, a lot of waste products will be generated during the production process, and the overall production cost remains high.

Abstract

The invention discloses a metal foil cleaning device for a lithium battery. The device comprises a cleaning solution smearing device, a cleaning solution recycling device, a pure water cleaning device, a waste water collecting groove, a drying device and a rack; two guiding rollers are arranged on the rack and are the first guiding roller located at the upper portion of the rack and the second guiding roller located at the lower portion of the rack; the cleaning solution smearing device and the cleaning solution recycling device are located in the front of the first guiding roller, the pure water cleaning device is located between the first guiding roller and the second guiding roller, after the drying device is located behind the second guiding roller, the waste water collecting groove isformed in the bottom of the rack behind the first guiding roller, and a spraying head of the pure water cleaning device and an air outlet nozzle of the drying device are located above the waste watercollecting groove. On a production site, a piece of metal foil is cleaned, the metal foil is cleaned at any time, coating of coatings can be performed at any time, the surface of the metal foil is coated with the coatings, and the quality of the lithium battery is improved.

Description

technical field [0001] The invention relates to the technical field of metal foil cleaning for lithium batteries, in particular to a metal foil cleaning equipment and cleaning method for lithium batteries. Background technique [0002] The working principle of a lithium battery is an electrochemical device that converts chemical energy into electrical energy. In this process, we need a medium to convert chemical energy into electrical energy and transmit it. Here, conductive materials are needed, and in ordinary materials First, metal materials are the materials with the best conductivity, and copper foil and aluminum foil are cheap and good conductivity among metal materials. At the same time, in lithium batteries, we mainly have two processing methods: winding and lamination. Compared with winding, the pole piece used to prepare lithium batteries needs to have a certain degree of flexibility, so as to ensure that the pole piece will not be brittle and broken during winding...
