carbon fabric

The electrochemical behavior of carbon-fabric electrodes in the pristine state and after modification with titanium (magnetron sputtering), silver (chemical precipitation) and sequential titanium/silver coatings was studied. The effect of metallic coatings on the conductivity, permittivity, and dielectric losses of model symmetric supercapacitors–fabricated using carbon-fabric electrodes, both with and without the coatings– was investigated.

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.
