BATTERY ALUMINUM FOIL COATING DEVICE, BATTERY ALUMINUM FOIL COATING METHOD, AND BATTERY

A battery aluminum foil coating device, a battery aluminum foil coating method, and a battery are provided. By sequentially passing the aluminum foil through an unwinding mechanism, a double-sided coating assembly, a first-sided coating assembly, a second-sided coating assembly and a winding mechanism to complete double-sided coating, the aluminum foil carbon layer coating process and the electrode slurry coating process may be combined, production cost may be reduced, production cycle may be shortened, and resource waste may be reduced.
