Food Grade Industrial Aluminum Foil Rolls Heat Sealing For Capacitor A1235-O

Aluminium/Aluminum Foil Purpose for Capacitor A1235-O 0.007-0.008mm
 
Product Description
 
The main components of lithium ion batteries include electrolyte, isolation materials, positive and negative materials, etc. The cathode consists of a current collector consisting of aluminium foil, lithium cobalt oxide or lithium ferrous phosphate. At present, the general battery foil products generally require strength more than 180 Mpa, and are pure aluminium alloy. That is to say, battery foil is a product that requires extremely strict aluminum foil base material. Battery foil is the product that requires the thinnest thickness, the highest strength, the highest surface factor, the smallest thickness difference, the best shape and the cleanest surface .
 
1235 Aluminium foil and 1060 aluminium foil are widely used on the aluminium foil for lithium ion batteries. The products have uniform surface color, clean, flat shape, no bright oil stain; strength > 180 Mpa, extension > 1.5%, wetting > 32 dyne, which can effectively improve the adhesion of active substances to collector and reduce manufacturing costs.
