The invention belongs to the technical field of polymer materials, and specifically relates to a method for preparing high-performance lead-acid battery shells by using recycled materials. The preparation method comprises adding fibrous crystals and compatibilizers into collected waste shell materials, mixing the raw materials thoroughly, feeding the mixture into an extruder for melting and blending, and extruding the molten material into a mold for molding to obtain finished lead-acid battery shells. By modifying recycled shell materials, the method enables recycled materials to meet the service requirements of new battery shells and reduce material waste. Moreover, the method is simple in process and easy for industrial implementation.
