Abstract：As battery foil products continue to develop in the direction of high strength,wide and ultra-thin,the quality requirements of the industry for battery foil are becoming more and more stringent.This paper puts forward the matching methods between battery foil process and equipment to product high-precision aluminum foil products based on the stability of the production process.Through controlling the bending force during thick material rolling,matching the equipment and process during cold rolling annealed materials,and controlling plate shape and selecting surface cleaning methods in the rolling aluminum foil process,the improvement and enhancement of the shape,surface cleaning,thickness,especially stability of battery foil products can be achieved.Production practice showed that,when rolling H18 state battery foil,maintaining the fluctuation range of the rolling mill's online bending force within-20%to 0%,controlling the thickness difference fluctuation in the stable zone within0.3%,the rolling speed within400～600 m/min,and the processing rate within 45%～50%,the quality of the shape and surface cleanliness of product are stable and reliable.
