제목 Effect of activated carbons/ manganese dioxide/polypyrrole for enhanced supercapacitor performances
초록 In this work, activated carbon/manganese dioxide (AM) composites synthesized with various weight ratio of tubular polypyrrole(T-PPy). The electrochemical performance, including capacitance and cyclic stability, of the resulting composites was investigated. The influence of the AM/T-PPy (AMP) content on the electrochemical properties and changes in pore structure were also examined. The morphology of composite was observed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The specific surface area of the composites was calculated from N2 77K adsorption/desorption isotherms by the Brunauer-Emmett-Teller (BET) equation. The electrochemical performance of the prepared composites was characterized by cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) measurements using an Ivium Stat electrochemical workstation (Ivium Technologies). The results prove that the AM/T-PPy ratio affects the electrochemical performance of supercapacitors.
