Food Insulation Aluminum Foil is used as a current collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the cathode current collector.
Rolled foil thickness varies from 10 to 50 microns. Commonly used pure aluminum foils for lithium batteries include various alloy grades such as 1060, 1050, 1145, and 1235, and are available in states such as -O, H14, -H24, -H22, and -H18.

Lithium batteries usually have two shapes: cylindrical and square. The battery adopts a spiral winding structure inside, and a very fine and highly permeable polyethylene film isolation material is used to separate the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and aluminum foil. The negative electrode consists of a current collector composed of graphitized carbon material and copper foil. The battery is filled with organic electrolyte solution, and is also equipped with a safety valve and PTC element (used in some cylindrical types) to protect the battery from damage in abnormal conditions and output short circuits.
