Pouch Cell Automation

Pouch Cell Automation
Automatic Production

The Formation and Grading System is a core equipment in lithium-ion battery production. It supports multiple models such as 18650 and 21700, with quick modular switching. Equipped with ±2℃ temperature control and energy feedback for energy efficiency, it integrates short-circuit, temperature, and smoke protection. It solves the problems of low precision and high cost of traditional equipment, and is suitable for large-scale production.

Technological Process

Process Flow:

Tray Loading—— Formation with Heating & Pressing—— Degassing —— Aging —— Grading—— OCV/IR Test —— Aging —— DCIR Test —— Storgae

the solution project

OCV/IR tester measure the voltage/ internal resistance of cells, store and upload the data to the database.

The tester is composed of control circuit module, test module, electric actuating unit, and sensing device module,etc.

Combined with charge-discharge system to realize grading process.

 Heating and pressing process with formation machine

① Temperature Monitoring in Each Layer
② Omnbearing Smoke Detection
③ Independent Temperature Sensor of Each Cell
④ Working 24 Hours Continuously



The shelve is made by steel; convenient transportation and installation.

Meets the need of long-term automatic operation of tridimensional storage system.
