Recently, many international automobile giants have accelerated their entry into the domestic automotive power battery industry, setting off a new round of joint venture climax in the automotive industry. Copper foil is one of the indispensable key materials for the production of power lithium batteries. As new energy vehicles enter another round of rapid upward phase, Lithium copper foil It will also enter a new business cycle.

China's demand for lithium battery copper foil will increase from 92000 tons in 2019 to 276000 tons in 2025, with a compound annual growth rate of about 21%. At the same time, with the high energy density and the increased recognition of Ningde Times as a leading enterprise representing lithium batteries, lithium battery copper foil, especially power lithium battery copper foil, will develop in the direction of 6 microns and below in the future, and the market share of extremely thin copper foil is expected to increase significantly.

Copper foil is the core material of negative collector of lithium battery, and the production process, cost and final product performance of lithium battery are closely related to the performance of positive and negative collector, that is, aluminum foil and copper foil.

In the production process of lithium battery, the cathode paste is usually coated on the copper foil of lithium battery, and then through drying, rolling, slitting and other processes, to obtain the cathode plate of lithium battery.

According to the industrial chain of lithium battery copper foil, lithium battery copper foil is mainly used for the manufacture of lithium battery cathode, and lithium battery is mainly used for new energy vehicles, 3C digital and energy storage systems.
