Sulfuric Acid Electrolyte

Abstract Activated carbons (ACs) based on wood charcoal were synthesized via sodium hydroxide activation and studied as electrode material in supercapacitors (sulfuric acid electrolyte). In focus were the porous structure of the ACs and their electrochemical properties as a function of the synthesis conditions. The data of surface area and pore volume and pore size dimensions (determined by N2 adsorption and evaluated based on three theories) of the ACs activated at 700°C and with NaOH/carbonizate ratios of 2 and 3.7 are reported, such as the specific capacitance (F g−1), specific resistance (Ohm cm), electrolyte volume (mm3 g−1) and the specific power capacity of a cell (Wh kg−1) of the supercapacitors made of various ACs. It was established that the porosity is increasing with increasing activation temperature and activator rate while the specific capacitance of the device increased up to 390 F g−1 based on elementary cell mass.

The article presents the results of a study of the process of obtaining a shiny nickel coating on steel from sulfuric acid electrolyte in the presence of an organic brightening additive - a de-rivative of rubeanhydric acid - under different modes of electrolysis. The expediency of using a nickel coating for corrosion protection of the housing of a high-pressure centrifugal pump has been substantiated
