The positive and negative electrode sheet of automotive power lithium battery is made by coating the positive and negative electrode material of lithium battery on the metal film. When coating the metal film on the electrode material, the metal film needs to be cleaned. The metal film is usually aluminum foil and copper foil. Plasma surface treatment can completely remove invisible organic matter, coarsening the surface, increase the wettability of metal film surface, improve the uniformity of coating layer, improve thermal stability, safety and reliability.

With the development of the automobile industry, sensor technology has been applied in a large number of modern automobile manufacturing, greatly improving the economic, power and emission performance of the automobile engine, improve the chassis braking performance, steering performance, car reversing and car driving safety performance. The resulting number of sensors is also increasing, and the performance of its various aspects of the higher and higher requirements, and the sensor packaging of the binding force and the joint surface of the bubble in the gap greatly affect the quality of the sensor requirements. If the sensor is treated by plasma, it can not only remove the non-volatile oil on the surface, but also greatly improve the surface activity of the sensor, and improve the adhesion strength between the inner wall of the sensor and the epoxy resin, avoid bubbles, improve the reliability and service life.

Plasma cleaning is a dry cleaning, which mainly relies on the "activation" of active ions in plasma to remove stains on the surface of objects and improve the surface energy. This method can effectively remove the dirt and dust on the end face of the core-pole, so as to prepare for the battery welding in advance and reduce the defective welding products. The plasma cleaner can participate in the lithium battery line, and can be seamlessly connected with other automation equipment for easy operation and monitoring.
