Manufacturing Method of Safety Lithium Battery

At present, there are three types of lithium batteries from the perspective of installation process: cylindrical, steel shell and soft case. In the current battery PACK technology, hard contact is used for cylindrical (prototype steel shell) and steel shell (square). The soft pack battery is also fixed in a small area after a group, and the battery body is in direct contact with the air. The advantage of this method is that the batteries are relatively stable, and air can flow between the batteries to dissipate heat. The disadvantage is that the battery is in contact with the air, and it is easy to cause a fire accident when a single cell is seriously heated.

The purpose is to provide a lithium battery automatic production line for the lack of existing lithium batteries. The lithium battery automatic production line can realize full automatic code scanning-injection-weighing-rehydration-sealing operation in the super purification glove box. Achieve efficient and completely unmanned automated production, greatly saving labor costs, greatly improving production capacity and product quality and yield, and maximizing benefits for customers. Production of new safety lithium batteries with high stability, high cost performance and long life.

Beneficial effect: The oven and the glove box are seamlessly connected to realize continuous production. The oven and the glove box are seamlessly connected. After baking, the battery core is always kept in a water-free and oxygen-free glove box environment. Fast cooling speed, the entire production line includes a cooling glove box, fast cooling speed, low cost, water-free and oxygen-free operating environment, to ensure that the cell from baking to filling, the sealing process is all in a controlled water-free and oxygen-free environment Operation, to provide the most solid protection for the quality of the battery. Ensure the stability of lithium battery cells and extend the life of lithium battery cells.
