In the development of new energy vehicles, the application of lithium batteries is one of the important part of energy-saving and emission reduction. Through the lithium battery charge and discharge to drive, the car can reduce the amount of gasoline to achieve clean emissions. Commonly used lithium battery foil is 1060 aluminum foil, 1050 aluminum foil, 8021 aluminum foil, 1235 aluminum foil and other alloy grades. There are -O, -H14, -H24, -H22, -H18 and other states.

In power lithium battery, the positive electrode is cobalt oxide, coated on the aluminum foil. The negative electrode is coated with graphite foil. Positive and negative directly with the diaphragm winding. Put positive and negative film on the battery shell, inject electrolyte vacuum packaging, to complete a single battery production. Cathode material accounts for about one-third of the cost of lithium batteries. Therefore, the positive electrode aluminum foil material in the lithium battery application prospects are very bright. Domestic aluminum foil manufacturers are also actively developing aluminum materials, new energy materials applications, such as aluminum batteries. At the same time, aluminum is also the main lightweight material. From the car body, to the fuel tank, radiator, automotive interior and other parts, aluminum, aluminum foil products are steadily growing trend in the continuous improvement of the car's aluminum level.

Aluminum foil's application in lithium batteries is the result of technological upgrading, but also aluminum foil manufacturers devote themselves to the results of research and development. With the guidance of government policy and the development of automobile production enterprises, new aluminum foil, aluminum materials in the automotive production applications will be more and more domestic aluminum foil should also keep up with the market, with this development trend for enterprises longterm development.
