| titleOfInvention | Aluminum foil for lithium ion battery, microporous aluminum foil and preparation method of microporous aluminum foil |
| abstract | The invention discloses an aluminum foil for a lithium ion battery, a microporous aluminum foil and a preparation method of the microporous aluminum foil, wherein the aluminum foil comprises 0.08-0.1wt% of Mg, less than or equal to 0.08 wt% of Si, less than or equal to 0.2 wt% of Fe, less than or equal to 0.03 wt% of Ga, less than or equal to 0.04 wt% of Cu, less than or equal to 0.04 wt% of Zn, less than or equal to 0.05 wt% of V, less than or equal to 0.03 wt% of Ti and 99.7 wt% of; preparing a microporous aluminum foil by adopting a chemical corrosion method; 300-6000 through holes and/or blind holes with the diameter of 6-12 mu m are distributed on each square centimeter of the microporous aluminum foil; compared with the existing series of aluminum alloy, the defined composition has higher yield strength, the pore diameter of the formed micropores is smaller and more uniform in the subsequent chemical corrosion process, the through holes and the blind holes are in arc transition with the material body, the stress concentration is reduced, the mechanical property is enhanced, the electrical property is not weakened, and the invention can be used in lithium batteries. |
