Electrolyte permeation table in dry production of Li-Mn button cells

Abstract

The invention discloses an electrolyte permeation table in dry production of Li-Mn button cells. The electrolyte permeation table comprises a worktable, a permeation support plate, a mainline belt support plate, a primary transfer driving belt pulley group, spindles, transfer belt groups, a secondary transfer driving belt pulley group, a belt group, a feeding cylinder, a feeding push shovel, a feeding sensor, primary and secondary transfer brackets and driven belt pulley groups. An assembly formed by injecting an electrolyte to a dry manganese plate and covering the manganese plate with a shell is fed to the permeation table through a feeding mechanism, by means of two conveying belt groups moving back and forth intermittently and a line shifting mechanism, after a few minutes of permeation, the electrolyte permeates the manganese plate fully, and the requirement for dry manufacture of cells is met. Full automation of the cell manufacture process is realized, working efficiency is increased greatly, long soaking time caused by soaking of manganese plate with excessive electrolyte in production is avoided, and zero emission of the electrolyte is realized.

Description

technical field [0001] The invention relates to the technical field of an electrolyte permeation table, in particular to an electrolyte permeation table in the dry production of lithium-manganese button batteries. Background technique [0002] The application and demand of lithium-manganese button batteries in industry and people's daily life products are increasing, from medical and military equipment to backup power for computers, automobile industry, power grid industry, various electronic products, toys, etc., various electronic products, etc. The application fields involved are becoming more and more extensive. The process flow of the existing lithium-manganese button battery automatic production line is: automatic negative electrode shell loading→cut lithium sheet→lithium sheet square and round→automatically cut diaphragm paper→inject electrolyte→ A series of key technologies such as adding manganese sheet→automatically closing the positive electrode shell→automatic se...

AI Technical Summary

Problems solved by technology

[0003] 1. Manganese flakes after drying need to be soaked in electrolyte solution. The soaking time is more than ten or even twenty hours. Sometimes vacuum soaking is used. The soaking time is long, the electrolyte is volatilized and wasted seriously, the battery manufacturing cost is high, and a large amount of electrolysis is required. There is danger in the liquid immersion process, the electrolyte is flammable, the fire hazard is serious, and the discharge of waste electrolyte seriously pollutes the environment;

[0004] 2. The production of the existing lithium-manganese button batteries is difficult to be automated with a low degree of automation, and it is difficult to adapt to the requirements of large-scale automated production. In the process of adding the wet sheet to the negative electrode shell, the exposure time of the wet sheet is too long, and the electrolyte volatilizes seriously. The performance of the battery is greatly affected. Therefore, we propose an electrolyte permeation platform for the dry production of lithium-manganese button batteries.
