| description | The invention discloses a soft package battery aluminum foil and a preparation method thereof.The method comprises the following steps that S1, a raw material formula is prepared into a cast ingot through a semi-continuous casting method; s2, the cast ingot is subjected to milling; s3, the milled cast ingot is subjected to homogenization heating treatment; s4, hot continuous rolling is conducted on the cast ingot obtained after homogenizing heating treatment, and a hot-rolled blank with the thickness ranging from 8.0 mm to 9.0 mm is obtained; s5, the hot-rolled blank is subjected to cold rolling, and an aluminum foil blank is obtained; and S6, the aluminum foil blank is sequentially subjected to foil rolling, slitting and final annealing, and the soft package battery aluminum foil is obtained. The surface quality of the prepared aluminum foil for the soft package battery is excellent, especially during double rolling, longitudinal stripes do not exist on the double face of the aluminum foil, the comprehensive |
