摘要

A new cheap asymmetric supercapacitor based on activated carbon (AC) and NaMnO₂ as electrodes and aqueous Na₂SO₄ solution as electrolyte was assembled. It shows an energy density of 19.5 Wh kg^-1 at a power density of 130 W kg^-1 based on the total mass of the active electrode materials and an excellent cycling behavior. This asymmetric aqueous AC//NaMnO₂ capacitor is promising for practical applications due to its low price, easy preparation of NaMnO₂ and friendliness to environment.
