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. At a charge-discharge current of 100 mA and a working voltage window of 1.2 V in 1 M solutions of iodide, sulfate and a sulfate/iodide mixture of 1 : 3 and 1 : 1, the specific discharge capacity values of the device were 40, 22, 44 and 37 F/g (160, 88, 172 and 148 F/g for the electrode), respectively. Benzotriazole either does not change or slightly reduces the specific capacity of the device.
