Adsorption-electrochemical modification of nanoporous carbon materials by nickel complexes with Schiff bases

Adsorption and subsequent polymerization of nickel(II) complexes with Schiff bases were studied in a porous carbon material used to manufacture electric double-layer capacitors (supercapacitors). The optimal modification conditions of the carbon material with polymeric complexes to obtain the maximum effect as regards the accumulation of electric energy in the supercapacitor were determined and substantiated. An effective and cost-efficient technique for modification of supercapacitor electrodes with electrically active polymers was suggested.
