Its interconnected Ni\u2013Co skeleton provides abundant active sites and low-resistance pathways for electron and ion transport, making it ideal as a current collector and substrate for Ni-MH and Ni-Zn batteries, supercapacitors and alkaline water electrolysis electrodes. The foam can be easily cut, punched and formed to size for both laboratory research and industrial production.<\/li>\n<li>This Ni\u2013Co foam features good mechanical strength and stable performance in alkaline electrolytes, and is widely used as a carrier for nickel\/cobalt hydroxide or oxide active materials. It is suitable for OER\/HER electrocatalysts for water splitting, fuel-cell catalyst supports and various electrochemical reactors. By replacing traditional metal plates or meshes, nickel cobalt foam helps reduce internal resistance, increase energy and power density, and extend the cycle life of energy storage and conversion systems.<\/li>\n<\/ol>\n<p><b><strong>\u0627\u0644\u0645\u0648\u0627\u0635\u0641\u0627\u062a<\/strong><\/b><\/p>\n<table>\n<tbody>\n<tr>\n<td><strong>\u0627\u0644\u0646\u0648\u0639<\/strong><\/td>\n<td>Open\u2011cell Ni\u2011Co alloy foam \/ nickel\u2011cobalt porous metal foam<\/td>\n<\/tr>\n<tr>\n<td><strong>Purity \/ Alloy Base<\/strong><\/td>\n<td>Ni\u2011Co alloy system (typically Ni as main component with Co as alloying element;
