Battery Foil

Aluminum and aluminum alloy battery foils are collectors for lithium ion batteries. Typically, the lithium ion battery industry uses rolled aluminum foil for battery aluminum foil for the positive electrode of the negative collector. The thickness of the rolled foil varies from 10 to 50 microns. Commonly used  aluminum foils for lithium batteries are 1060, 1050, 1145, 1235 and various other alloy temper in -O, H14, -H24, -H22, -H18 etc.
