What is the thickness and alloy standard for battery aluminum foil?

News Details

Aluminum foils are good thermal conductivity and electrical conductivity, which used in the production of lithium-ion batteries. The battery aluminum foil is mainly divided into series 1 and series 3. The commonly used alloy aluminum foil are 1050, 1060, 1235 and 3003 aluminum foil.


battery aluminum foil thickness

The thickness of the battery aluminum foil is between 10 and 50 microns. Its quality and appearance requirements are very high, for example, the surface of the aluminum foil should be uniform, clean and flat, without obvious curl marks, pinholes, corrosion marks, no bright spots, no color difference, no serious smell, and the dyne pen test used to test surface tension is not less than 32 dynes.
