 Filling
 

Filling: We have nearly 500㎡ hothouse. The USA MUNTERS dehumidification equipments can ensure the HR is under 1%(dew point〈-40℃〉). Under the very dry condition, we adopt vacuum filling to reduce the water-absorbing rate of electrode boards and electrolyte a lot; We use pumps with high precision to keep good consistency of filling quantity.

 

 

Automatic sealing: The automatic capper developed by ourselves has many advantages, for example, high sealing speed, stable sealing pressure, good consistency of steel balls height. This capper can prevent moist air from entering after pre-formation, which can improve cycle and safety performance and control the distension of battery.
