When traditional copper busbars are connected in battery packs, it is common for the wiring joints of the copper busbars to dissipate heat too slowly, resulting in line aging. This type of copper busbar has poor heat resistance. Usually, the heat dissipation effect of copper busbars is poor, and the heat dissipation is easily retained within itself, which affects the transmission efficiency of copper busbars. And in the face of some collision situations, the copper busbars cannot protect the wiring terminals. The process of immersing the copper busbars in plastic is adopted to solve this problem.
The impregnation molding process for battery copper busbars is a common metal surface treatment process. Firstly, clean the surface of the copper busbar to remove any oil and oxides on the surface. Then, immerse the copper busbar in a special impregnation solution for a period of time to form a uniform layer of plastic film on the surface of the copper busbar. Place the impregnation treated copper busbar in a well ventilated area to cure the plastic film on the surface of the copper busbar. Trim the cured copper bar to remove surface burrs and unevenness.
The copper busbars treated with impregnation have good corrosion resistance and wear resistance, improving product performance while also enhancing product aesthetics. YIPU Metal is a professional manufacturer of copper busbars, and our copper busbar products are mainly used in the fields of energy storage and battery packs.
