Lithium ion battery core production system

Abstract

The invention discloses a lithium ion battery core production system, which comprises a bottom box and a top box fixedly mounted at the top of the bottom box through supporting columns, wherein a hydraulic lifting mechanism is fixedly mounted at the bottom of the inner wall of the top box through a mounting frame, a charging jig is arranged at the extending end of the hydraulic lifting mechanism,a partition plate is fixedly connected between the two sides of the inner wall of the bottom box, and an immersion cylinder is fixedly installed at the bottom of the inner wall of the bottom box through a connecting plate. The invention relates to the technical field of lithium ion battery productcion. According to the lithium ion battery core production system, the battery core can be completelyprevented from being completely not in contact with the outside before being pressurized and formed, and the three procedures of baking, electrolytic solution filling and pressurizing and forming arewell integrated into one piece of sealing equipment to be completed, so that the problem of secondary pollution caused by contact between the battery core and the outside in the processing process iswell solved, subsequent processing procedures do not need to be carried out through multiple times of transfer, and the production process is simple.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium ion battery cell production system. Background technique [0002] Lithium-ion battery is a kind of secondary battery, which mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li + Intercalation and deintercalation back and forth between two electrodes: when charged, Li + It is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging. The preparation method of the lithium-ion battery cell is as follows: [0003] 1. Match the positive and negative plates, add insulating diaphragm paper and wind them up. [0004] 2. Put the rolled battery core into the shell, weld the cap, and perform laser welding to seal. [0005] 3. Put t...

Problems solved by technology

[0014] Aiming at the deficiencies of the prior art, the present invention provides a production system for lithium-ion battery cells, which solves the problem of cumbersome transfer of existing lithium-ion battery cells in the transfer production process, and the long exposure time is easy to be polluted, which affects the quality of the cells. The quality of the product cannot completely solve the problem of secondary pollution caused by the contact with the outside world during the processing of the battery, and the production efficiency is low, the production cost is high, the production is cumbersome, and the production flexibility of the battery processing equipment is poor.
