The invention relates to a production method for improving the dyne value of the surface of a battery foil, which ensures the strength and thickness of an oil film on the surface of the battery foil in the foil rolling process by controlling the composition and proportion of lubricating oil for rolling the battery foil, the roughness of a working roll and a grinding wheel. The aluminum powder generated in the normal rolling process can be adsorbed and taken away by rolling oil, meanwhile, the roughness of rough rolling, intermediate rolling and finish rolling working rollers of foil rolling working rollers is controlled to be gradually reduced step by step to form a fall, and lubricating oil is matched, so that the falling amount of the aluminum powder on the surface of the battery foil in the rolling process is gradually reduced. The method can improve the dyne value of the surface of the battery foil and improve the surface quality of the aluminum foil. 本发明涉及一种改善电池箔表面达因值的生产方法，本方法通过控制电池箔轧制用润滑油的组成及配比、工作辊粗糙度及磨
