Problems solved by technology

[0002] The production and manufacture of lithium batteries requires a specific environment. A small leak may destroy the balance of water and oxygen content, thereby affecting the quality of battery production, especially to meet the requirements of process improvement and meet the special environmental requirements of battery pole piece pre-lithiation, that is, battery production The environment requires water and oxygen content ≤ 1PPM. At the same time, the production and manufacturing of lithium batteries are often processed separately according to the process. There is no modular production line, and the production efficiency is low.

Abstract

The invention discloses a soft-pack lithium battery trial production line in a glove box environment and its production process, and relates to the field of lithium battery manufacturing equipment. Heat-sealing device, liquid injection-formation device, wherein, the heat-sealing device and liquid injection-formation device are connected through a vacuum purification transition chamber, and the glove box sealing cover is arranged on the frame so that the lamination device, welding device, heat-sealing The device, liquid injection-formation device is isolated from the outside world, and the glove box is filled with inert gas. The battery trial production line of the present invention is divided into modules according to the process units. At the same time, a glove box is provided on the sealing cover of the battery trial production line to ensure the environmental requirements of battery production. Battery manufacturing efficiency.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing equipment, in particular to a soft-pack lithium battery trial production line in a glove box environment and a production process thereof. Background technique [0002] The production and manufacture of lithium batteries requires a specific environment. A small leak may destroy the balance of water and oxygen content, thereby affecting the quality of battery production, especially to meet the requirements of process improvement and meet the special environmental requirements of battery pole piece pre-lithiation, that is, battery production The environment requires water and oxygen content ≤ 1PPM. At the same time, the production and manufacturing of lithium batteries are often processed separately according to the process. There is no modular production line, and the production efficiency is low. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the pres...
