Lithium battery pure aluminum spacer, made of high - purity aluminum, have good thermal conductivity, corrosion resistance and mechanical strength. They fill gaps, ensure flatness, and are used in lithium - ion batteries for functions like heat dissipation and component connection, enhancing battery performance and safety.
The principle of c is to use the energy generated by the high-frequency mechanical vibration of ultrasonic waves to weld non-ferrous metal materials of the same or different types.
