Aluminum foil plays an important role in lithium-ion batteries
Source:
Lithium ion batteries usually use aluminum foil as a positive current collector. In order to stabilize the current collector inside the battery, the purity of the aluminum foil used is required to be above 98. Therefore, the battery aluminum foil to 1 series of pure aluminum foil, commonly used brands 1060, 1050, 1235 aluminum foil, etc., there are O, H14, H24, H22, H18 and other states.
In life, lithium batteries are generally used in digital products and new energy vehicles. No matter where they are used, people hope that the energy density of the battery will be as high as possible. With the continuous development of technology, the weight of lithium batteries is getting lighter and lighter, the thickness and weight of current collector materials are gradually decreasing, and the volume and weight are decreasing. Especially in new energy vehicles, there are certain requirements for battery life and body weight. The 1235 aluminum foil for lithium batteries has a low density and light weight, which is very helpful for reducing the weight of the car body.
1235 aluminum foil aluminum element content of not less than 99.35, has good anti-rust characteristics, formability, solubility, and is well used in lithium batteries.
