Lithium battery aluminum foil produced by Mingtai


Under normal circumstances, lithium battery aluminum foil as a positive electrode collector, commonly used aluminum foil is a series of pure aluminum foil, including 1060 aluminum foil, 1050, 1235 and other grades, the state is O, H14, H18, H24, H22, thickness of 10 to 50 microns between. The choice of battery aluminum foil is very important and has a great impact on battery performance. Among the total procurement costs, cathode material procurement costs account for 30%, and anode materials account for 20%.The surface quality of the battery aluminum foil has certain requirements, including: 1 The surface of the aluminum foil is uniform in color, clean, and flat. 2 The surface of the aluminum foil has no rolling defects such as creases, spots, and bright lines; there are no pinholes and corrosion marks. 3 The surface of the aluminum foil is oil-free, has no serious oil odor, and no oil spots are visible to the naked eye. 4 Surface tension test is not less than 32 dynes. Lithium battery aluminum foil anode aluminum foil has no special requirements on the performance of aluminum foil.In new energy vehicles, lithium batteries play an important role. On the one hand, the positive electrode of the lithium battery is aluminum foil, which can reduce the weight of the car itself. On the other hand, the reduction in body weight can also increase the cruising range of new energy vehicles.
