4 V class aqueous hybrid electrochemical capacitor with battery-like capacity

Author affiliations

Abstract

A new aqueous hybrid electrochemical capacitor consisting of a porous positive capacitive electrode and a water-stable multi-layered Li negative electrode is demonstrated. The new cell design affords cell voltages close to 4 V in a mild aqueous electrolyte. Application of a pseudocapacitive positive electrode with high specific charge results in specific energy comparable to present rechargeable batteries.
