High-voltage aqueous battery approaching 3 V using an acidic-alkaline double electrolyte

Chem Commun (Camb). 2013 Mar 18;49(22):2204-6. doi: 10.1039/c3cc00064h.

Abstract

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.
