Device and method for removing water from a cell

Abstract

The invention relates to a water removal device and method suitable for laser-cut batteries, in particular to a water removal device and method for batteries, which are used to solve the problem of drying batteries by heating transmission belts in existing battery water removal devices. Surface moisture requires a high drying temperature and a long time, and will cause thermal damage to the battery sheet. After the water evaporates, its impurities will remain on the surface of the battery sheet. The cell water removal device includes a water removal mechanism, a slice mechanism and a connection mechanism, wherein the water removal mechanism includes a second water removal component for absorbing moisture from the battery sheet to be dewatered and removing impurities on the surface of the battery sheet to be dewatered, And the first dewatering component for absorbing moisture from the second dewatering component. Meanwhile, the present invention discloses a method for removing water from a battery based on the above water removal device for a battery.

Description

technical field

[0001] The invention relates to a water removal device and method suitable for laser-cut battery sheets, in particular to a battery sheet water removal device and method. Background technique

[0002] In recent years, the use of laser cutting cells has received more and more attention. Its working principle is to use high-energy laser beams to irradiate the surface of the cells to heat the irradiated parts, and then spray water on the spot to cool the cells. This creates thermal stress that grooves the surface of the cell.

[0003] In order to prevent oxidation and pollution of the cells, the water spray surface near the position of the battery slot needs to be dewatered. The current dewatering method for the cells is to use a heated conveyor belt to dry the surface moisture of the cells, which has the following defects : (1) It takes a long time to dry at high temperature, which increases the production cost; (2) Excessive temperature may cause thermal dama...
