EFFECTS OF GRAPHENE-BASED PHASE ADDITION TO THE PRECURSOR OF THE NANOPOROUS CARBON ON ELECTROCHEMICAL PERFORMANCE OF THE RESULTING CARBONACEOUS COMPOSITES

摘要

Introduction Graphene/reduced graphite oxide (rGO) is an interesting component of different energy storage devices. Combining unique conducting properties of graphene and porous structure of activated carbon can lead to an improvement of the electrochemical performance of carbon-based supercapacitors. The results obtained on carbon/graphene composites are analyzed in terms of (i) the contents of rGO phase and related to it DC conductivity, (ii) the sizes and volumes of pores, (iii) the presence of specific functional groups, and (iv) their effect on the capacitance of the composites. The results are expected to further clarify the influence of graphene-based phase on the performance of carbonaceous materials as electrochemical capacitors.
