Copper Electro-Formed Gauze is a material known for high electrical conductivity, mechanical strength, and corrosion resistance. It is commonly applied as a current collector in lithium-ion batteries, supercapacitors, and fuel cells, due to its consistent mesh structure and ability to support efficient charge transfer. The gauze also functions in filtration systems and electrochemical devices, providing a high surface area conductive mesh for effective particle and fluid separation. Researchers use copper electro-formed gauze in gas detection sensors and electrochemical monitoring systems, where its electrochemical stability, fast response times, and fine mesh resolution make it suitable for industrial sensing and environmental monitoring applications. Its role in energy storage and sensor technologies makes it a valuable material in materials science laboratories and flexible electronics research.
