Battery copper foam ultra-thin copper foam nickel foam new energy-saving material

1. Pore characteristics and volume density pore size) Porosity and porosity ≥ volume density / 2. Main characteristics) Copper foam has excellent thermal conductivity and can be widely used for heat conduction and heat dissipation of motors/electrical appliances and electronic components) Copper foam has its electrical conductivity Excellent, its application in electrode materials of nickel-zinc batteries and electric double layer capacitors is also receiving attention from the industry) Due to the structural characteristics of copper foam and its basically harmless characteristics to the human body, copper foam is also an excellent medical filter material and water purification filtration materials are three application fields of electrode materials. Excellent conductive properties enable copper foam to be widely used as electrode skeleton materials for new batteries such as nickel-zinc battery double-layer capacitors. Currently, copper foam has been trialled by many nickel-zinc battery manufacturers and put into batch use. At the same time, copper foam It is expected to be widely used as an electrode current collector for electric double layer capacitors. In addition, copper foam also has very broad prospects for use as an electrode material for electrolytic recycling of copper-containing wastewater. catalyst. In many organic chemical reactions, people have tried to directly use copper foam with a large specific surface area to replace punched copper plates. As a chemical reaction catalyst, copper foam has also been successfully used as a photocatalytic air purification carrier. Thermal conductive materials. Copper foam has excellent thermal conductivity, making it a flame-retardant material with excellent performance. It has been used in many advanced fire-fighting equipment abroad, especially as a flame isolation equipment. In addition, people use the excellent thermal conductivity of copper foam and With apparent permeability, it can be made into heat dissipation materials for motors and electrical appliances. Sound deadening and shielding materials. Sound waves diffusely reflect on the surface of copper foam, and achieve the effect of silencing through the principle of expansion and silencing micropores. The shielding performance of copper is close to that of silver, and it is an electromagnetic shielding material with excellent performance. filter material. Copper foam products, which have excellent structural properties and are basically harmless to the human body, have also been successfully used as medical filter materials. At the same time, copper foam also has good prospects for use in water purification devices. Fluid pressure cushioning material. The dispersion and buffering effects of copper foam on fluids make it effective as a pressure reduction protection device for various pressure instruments.
