Abstract:
In this work, three-component electrode materials based on a composite of polyaniline with multi-walled carbon nanotubes and carbon blck were obtained, which are promising for supercapacitor electrodes. The method proposed in the work allows achieving a uniform distribution of polyaniline over the surface of carbon black particles in the form of layers with a thickness of $\sim$5 nm, which ensures high porosity and specific surface area. It is shown that the presence of carbon black in the material composition leads to a decrease in the degree of defectiveness of the polymer structure. With an increase in the proportion of carbon black, the electrochemical characteristics of electrode materials increase: the speed capacity of the electrodes (up to 81%) and their cyclic stability (92%) compared to a composite that does not contain carbon black (25% and 78%, respectively).
Keywords:composites, XPS, cyclic voltammetry, specific capacitance.
