Its interconnected sponge\u2011like structure provides abundant active sites and low\u2011resistance pathways for electron and ion transport, making it an attractive self\u2011supported substrate for electrocatalysis, CO\u2082 reduction, electroplating, and advanced battery and supercapacitor electrodes. The foam can be easily cut, punched and shaped to fit different cell designs in laboratories and pilot lines.<\/li>\n<li>Cu\u2011Sn foam combines the conductivity and mechanical strength of copper with the alloying properties of tin, which can improve electrochemical behavior for applications such as Li\u2011ion\/S batteries, Na\u2011ion batteries, electro\u2011reduction and catalyst supports. It can be supplied in different thicknesses and pore sizes (PPI), and can be further coated with active materials to increase capacity and catalytic activity. Copper tin foam is suitable for researchers and manufacturers looking for a cost\u2011effective, high\u2011surface\u2011area porous current collector for energy storage and conversion
