Abstract: A method for preparing a supercapacitor electrode material Ni doped CoP3/Ni foam is provided, and the CoP3 is applied to the supercapacitor for the first time. The method belongs to a technical field of synthesis and preparation of supercapacitor materials. The present invention adopts a low-temperature phosphating process to prepare the Ni-doped CoP3/foamed nickel as the electrode material of the supercapacitor, so as to provide advantages such as simple synthesis process, easy control, low cost and high specific capacity. The supercapacitor electrode material Ni doped CoP3/Ni foam prepared by the present invention has a hierarchical structure and a large specific surface area, which is beneficial to shorten an ion transmission path, reduce an interface resistance between the electrode material and electrolyte, provide more active sites, and provide a higher specific capacity in alkaline electrolyte. The electrode material shows great potential in electrochemical energy storage.
