Abstract The utilization of electrode materials could be greatly promoted by the employment of a mesh-type stainless steel (SS) current collector in comparison with a plate-type one. The capacitive behavior of activated carbon (AC) and AC–ruthenium (AC–Ru) composites fabricated by the wet impregnation were systematically investigated in 0.1MH2SO4 by cyclic voltammetry (CV) and chronopotent…
Abstract The effects of annealing in air and anodizing on the capacitive behavior of carbon–ruthenium (denoted as C–Ru) composites fabricated by wet impregnation were investigated in 0.1 M H2SO4 by cyclic voltammetry (CV) and chronopotentiometry (CP). The utilization of Ru species within the thick composites (-1000 lm) was greatly promoted by annealing in air at 240 -C for 8 h and anodizin…
Abstract The capacitive characteristics of activated carbon fabrics (ACFs) coated on the graphite substrates were systematically investigated by means of cyclic voltammetry and the galvanostatic charge–discharge technique. Effects of the PVDF contents in the electronically conductive binder, electrochemical pretreatments, and the electrolytes on the capacitive performance of ACFs were compar…
