Реферат: Electrochemical properties of a cell with carbon highly porous electrodes and a solid polymer electrolyte based on polyurethane elastomer filled with a solution of an organic salt of N,N-methyl-propyl-piperidinium in N-methyl-2-pyrrolidone have been studied. The values of specific capacitance of the electrode material in contact with the polymer electrolyte, which reach 45 F/g, were determined by cyclic voltammetry (CVA) in the voltage range from –4.5 to 4.5 V and galvanostatic charge-discharge. Analysis of the dependence of capacitance on the potential sweep rate has shown that the main contribution to the capacitance is the pseudocapacitance due to surface electrochemical processes, the nature of which is still unclear. The CVA data are in good agreement with the data obtained by impedance spectroscopy. The obtained polymer solid electrolyte based on polyurethane elastomer can be used to create flexible polymer supercapacitors operating in a wide voltage range.
