Abstract

A hierarchical porous MnO2 electrode is developed to enhance ionic liquid electrolyte transport and increase electroactive sites for charge-storage reactions. Superior cell energy and power densities of 90 W h kg−1 and 43 kW kg−1 were obtained, which are one-order higher than those for a conventional MnO2 cell with an aqueous electrolyte.
