99.9% Purity Cu Copper Foam For Lithium ion Battery Cathode Material
Product Introduction
Due to its good electrical conductivity, copper foam can be widely used as electrode skeleton material for new batteries, such as nickel-zinc batteries and double-layer capacitors. Copper foam is expected to be popularized as the collector of double layer electrode for capacitor application
Product Characteristics
Copper foam is used as a collector for battery anodes. Copper foam is relatively easy to manufacture, with a three-dimensional structure, which can increase the surface area of the electrodes, closer to each other, thereby increasing the current density. The complex three-dimensional structure is used for electrode materials instead of flat surfaces. The material is more efficient.
Copper foam enhances the heat dissipation of the battery; under forced convection, the porosity remains the same, the pore density increases, and the battery heat dissipation is weakened; when the pore density is the same, the porosity decreases, and the battery heat dissipation is enhanced; under natural convection, the porosity is the same, and the pore density increases, and the battery heat dissipation is enhanced.

How to make copper foam?
Copper foam is a new type of multifunctional material with a large number of connected or non-connected pores evenly distributed on the copper matrix. Copper foam has good conductivity and ductility. Compared with nickel foam, it has low preparation cost and good conductivity, and can be used to prepare battery negative electrode (carrier) material, catalyst carrier and electromagnetic shielding material. In particular, foamed copper has some obvious advantages as a substrate for battery ele...
