Product Details:
Specifications: Provide double-sided bright lithium copper foil of different widths, with a nominal thickness of 8 to 35 micrometers..
Application:
Double-sided lithium battery copper foil is an important component of lithium batteries. As the negative electrode current collector, it not only carries the negative electrode active materials but also is responsible for collecting and conducting electrons, which is crucial for the performance and safety of the battery. With the rapid development of fields such as new energy vehicles and energy storage systems, the requirements for the energy density and safety performance of lithium batteries are getting higher and higher, and the application of double-sided lithium battery copper foil is also becoming more and more widespread.
Double-sided lithium battery copper foil is mainly used in fields such as new energy vehicles, electric bicycles, 3C electronic products, and energy storage systems. It is also
Used as the negative electrode carrier and liquid collector of lithium-ion batteries.
