Electrical Double-Layer Capacitors Based on Carbon Electrodes

Electrical Double-Layer Capacitors Based on Carbon Electrodes 

In fact, parameters closely connected with the SSA - pore volume of carbons, size and shape of pores, tortuosity - play an important role in charge storage. 

In organic TEABF electrolyte, good electrochemical performance and mechanical stability was observed for electrodes with 3.5 wt% of polyvinylpyrrolidone (PVP) binder [61]. This amount of PVP has a negligible impact on porous texture characteristics, with total pore volume of 0.71cm g as compared to 0.73 cm g for the as-received AC. ECs with AC-PVP, AC-PTFE, and AC-PVdF electrodes in 1 mol l TEABF in PC exhibited specific capacitance values of 112, 107, and 70 Fg , respectively. Hence, this fluorine-free material appears
