摘要: We demonstrate for the first time that incorporation of a redox-active molecule in an organic electrolyte can increase cell voltage supercapacitor. The redox also contributes to increasing capacitance by faradaic reaction, and therefore energy density supercapacitor be significantly increased. More specifically, addition decamethylferrocene results approximately 27-fold carbon-nanotube-based supercapacitors. resulting high (36.8 Wh/kg) stems from increased (1.1 V → 2.1 V) (8.3 F/g 61.3 F/g) addition. found is associated with potential species relative electrochemical stability window supporting electrolyte. These will useful identifying new electrolytes high-energy-density
