High-voltage aqueous battery approaching 3 V using an acidic-alkaline double electrolyte.
Based on an acidic-alkaline double electrolyte, we designed and fabricated a novel Zn/KMnO(4) aqueous cell with a high operating voltage of 2.8 V. The theoretical energy density of this aqueous cell is even compatible with organic electrolyte-based lithium batteries.
