Abstract
The paper is devoted to the application of composite electrochemical coatings with cadmium nanopowder as anode material of alkaline electrolyte supercapacitor. It is shown that composite coatings with cadmium nanopowder are promising anode materials for alkaline electrolyte supercapacitors having specific capacitance of 140-180 F/g. The cadmium powder-cadmium composite coating has a higher specific capacitance than the nickel powder-cadmium composite. The electrode processes enabling the operation of the electrodes are cadmium oxidation to cadmium hydroxide and cadmium hydroxide reduction. In the case of nickel-powder cadmium composites, a double layer component of specific capacitance is also present, which allows the analysis of Ragone diagrams.
