| description | The invention discloses a battery aluminum foil and a preparation method thereof.The preparation method comprises the following steps that S1, raw materials are smelted into molten aluminum according to a formula; s2, the molten aluminum is injected into a casting nozzle of a casting and rolling machine through a runner, the molten aluminum is cooled through a rolling roller of the casting and rolling machine, and a cast-rolled coil is obtained; s3, the cast-rolled coil is subjected to cold rolling through a four-roller cold rolling mill, and a cold-rolled coil is obtained; and S4, carrying out foil rolling on the cold-rolled coil through a foil rolling mill to obtain the battery aluminum foil with the thickness of 0.01-0.015 mm. The thickness of the battery aluminum foil prepared through the preparation method is 0.01-0.015 mm, the tensile strength is larger than 250 MPa, the ductility is larger than 5%, the surface appearance is free of color difference and bright line defects, it is guaranteed that the pla |
