сульфат натрия

The energy characteristics of prototypes of supercapacitors with carbon fabric electrodes Busofit T-040 were studied depending on the concentration of aqueous solutions of sulfate, sodium iodide and their mixtures without and in the presence of a corrosion inhibitor of the nickel collector – benzotriazole. It was found that the specific capacity of devices based on sodium iodide is almost two times higher than in the case using sulfate media. Close values of specific capacitance were obtained in devices based on mixed electrolytes.

The energetic properties of the new composite electrode materials suitable for electrochemical capacitors were investigated. Composite electrodes were made using Norit A activated carbon and synthesized sparingly soluble copper salts such as copper iodide(I) and hexacyanoferrates (II), etc. (III). The composition of the salts was confirmed by elemental analysis and the particle size was determined by the Scherrer equation using the data of X­-ray phase analysis.
