Color treatment process for aluminum shell of power lithium ion battery

Power lithium-ion battery aluminum shell generally uses 3003 aluminum alloy as an important material, because the power lithium-ion battery aluminum shell made of this material has the characteristics of explosion-proof, high temperature resistance, and corrosion resistance. The production process of power lithium-ion battery aluminum shell generally requires color processing, but many people don’t know what the color processing process is. The following is an explanation of the color processing process of power lithium-ion battery aluminum shell by technicians from the Asian continent: Step: Surface pretreatment cleans the aluminum surface of the power lithium-ion battery by chemical or physical methods to expose the pure matrix to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matte) surface by mechanical means. Step 2: Anodizing Under certain process conditions, the aluminum shell of the power lithium ion battery with the surface pretreatment is anodized on the surface of the substrate to form a dense and porous strong adsorption layer AL203. The third step: the sealing hole seals the pores of the anodized porous oxide film, which improves the anti-pollution, corrosion resistance and abrasion resistance of the oxide film. The oxide film is colorless and transparent. Before using a strong adsorption oxide film to seal the holes, the metal salt is adsorbed and deposited on the film pores, which can make the appearance of the aluminum shell of the power lithium ion battery appear natural (silver-white), such as: black, copper, gold and stainless steel s color. This is the end of the process of coloring the aluminum case of the battery. The aluminum shell battery of the aluminum shell is colored. It is important to make a mirror on the surface of the aluminum shell more beautiful. The aluminum shell of the power battery will not fade after coloring. We have discussed the surface treatment technology of the aluminum shell of the power lithium ion battery, you can know Combined.
