The electrochemical performance of MnO2 nanorods prepared by a precipitation reaction was investigated in 0.5 mol/L Li2SO4, Na2SO4, and K2SO4 aqueous electrolyte solutions. Results show that at the slow scan rates, largest capacitance (201 F/g) Li2SO4 since reversible intercalation/deintercalation Li+ solid phase produces an additional besides based on absorption/desorption reaction. At fast rates they due to smallest hydration radius K+, highest ionic conductivity, lowest equivalent series...
An asymmetric supercapacitor (ASC) is a based on two different electrode materials. One redox (Faradic) reactions with or without non-faradic reactions, and the other one mostly electric double-layer (non-Faradic electrostatic) absorption/desportion. Aqueous electrolytes have higher ionic conductivity, larger capacitance better safety than organic electrolytes. Herein, some key materials for aqueous ASCs are primarily reviewed, which provide new direction power sources to energy density at...
