How to clean the battery aluminum shell?

Aluminum is a high energy carrier and an ideal electrode material for battery development. Aluminum has not been successfully applied in electrochemical energy storage and conversion technology because of a protective film on the surface of aluminum metal, which has a significantly lower electropolar potential than the theoretical value and a significant lag in voltage behavior. In the activated state, the corrosion resistance of aluminum decreases, which limits the early development and application of aluminum batteries. In recent years, through the development of various new aluminum electrode and the corresponding electrolyte additives, the research of aluminum battery has made a breakthrough progress, opened up a new field of aluminum electrochemical application. Electrolyte is produced on the surface when electrolyte additives are added. If the surface electrolyte is not cleaned thoroughly, the aluminum shell will be seriously corroded and the appearance of the product will be affected. In recent years, in order to remove the electrolyte on the surface of the battery aluminum shell, the ultrasonic cleaning machine has been developed. Battery aluminum shell, ultrasonic cleaning trough ultrasonic cleaning machine is mainly composed of ultrasonic solution of coarse rinse tank, ultrasonic rinse tank, filtering cycle system and automatic temperature control of heating system, four solutions produced by not steel quality ultrasonic cleaning tank, ultrasonic washing tank, ultrasonic washing tank of a cleaning equipment can work continuously
