There are two reasons for using aluminum foil as the positive electrode collector of lithium-ion batteries: firstly, the dense oxide layer on the surface of aluminum and its high chemical potential can prevent the collector from oxidation and corrosion by the electrolyte, and at the same time, lithium embedding reaction will not occur; secondly, using aluminum foil as the collector can greatly reduce the contact resistance between the positive/negative electrode materials and the collector and improve the adhesion ability between the two, which can significantly improve the range of electric vehicles. This can significantly improve the range of electric vehicles.

The quality and cost of aluminum foil for batteries are relatively low, and it is relatively hidden in the composition of lithium batteries. Battery aluminum foil accounts for 5% by weight, next to positive materials, negative materials, electrolyte and copper foil; the cost accounts for about 3% of the total cost of lithium battery, next to positive materials, diaphragm, negative materials, copper foil and electrolyte, so it is easy for people to overlook its importance due to its low quality and cost.
