XIAMENLithium Ion Battery 8micron Copper Foil -Double faced smooth
SPECIFICATIONS
Copper foil is a thin sheet or film made of high-purity copper, with a thickness usually ranging from a few microns to tens of microns. It has excellent electrical conductivity, thermal conductivity, flexibility and mechanical strength, and a smooth and uniform surface. The production process of copper foil mainly includes electrolysis and calendering. According to different uses, it can be divided into standard copper foil, ultra-thin copper foil, high ductility copper foil, etc.
Main characteristics:
High conductivity: Copper foil has excellent electrical conductivity and is suitable for occasions requiring efficient current conduction.
Flexibility: It has good bending and stretching properties and adapts to complex shapes and dynamic applications.
Surface flatness: The surface is smooth and suitable for subsequent processing such as coating and etching.
Corrosion resistance: After surface treatment, copper foil can have certain antioxidant and corrosion resistance.
Thickness diversity: The thickness range is wide, from a few microns to tens of microns, meeting different application requirements.
Application
Battery industry
Lithium-ion battery negative electrode current collector: Copper foil acts as a carrier of negative electrode material, conducts current and supports active substances. It needs to have high conductivity, good flexibility and mechanical strength to support repeated charging and discharging of the battery.
Power battery: high-performance battery for electric vehicles and energy storage systems.
Ultra-thin copper foil: used for high energy density batteries to improve battery performance.
New energy field
Solar cells: copper foil is used for the conductive layer of solar cells to improve the photoelectric conversion efficiency.
Fuel cells: as the conductive component of fuel cells, it supports efficient energy conversion.
