High-temperature Pressure Forming Equipmen
At present, a heating clamp is used to press the two sides of the battery during the production process of soft package batteries. The gas during the formation can be discharged into the airbag under the pressure, so that the electrolyte can be fully infiltrated and form a good SEI film during the formation of the battery cells.
Details

Test Items

1. Battery cell forming performance test

2.Battery cell temperature acquisition, monitoring test

3. Battery cell compression stressed test


Functional Characteristics

1. During hot pressing, the battery is heated to increase the fluidity of the electrolyte, so that the viscosity of the electrolyte is high, and the electrolyte is fully infiltrated, easy to form a dense SEI film, in favor of extending the cycle life of the cell. The battery cell is rapidly cooled and shaped into formation by cold pressing, which can control the shape of the battery cell. This type of hot-pressed battery cell has the advantages of good active material performance, low probability of bump, long cycle life and so on.

2. For the horizontal hot pressing mode, the servo screw option is adopted for the clamp, indicating uniform pressure transmission, with the pressure control error ≤10kgf.

3. Heating press fixture adopts electric heating method, with the temperature to be flexibly adjusted according to the actual condition. The maximum design temperature is 90° C. The uniformity of the temperature between all the laminates of the hot press fixture is ≤±2° C. The temperature rise time of the hot press fixture rising from room temperature to 80°C is ≤ 40 minutes.

4. The fixture is compatible with both unilateral lug and bilateral lug type, capable of quick change, able to meet the clients' personalized customized demand.

5. The lug crimping mechanism is made of special alloy material and the contact resistance is less than 2mΩ, which can reduce pressure drop of power supply and temperature rise of the lug. The large-current hot pressing formation test is performed, in favor of shortening the formation time, hence to reduce the cost.
