Aqueous Rechargeable Lithium Battery Based on LiNi0.5Mn1.5O4 Spinel with Promising Performance

By virtue of their different electrode potentials, Li1-xMn2O4 (LMO) and LiNi0.5Mn1.5O4 (LNMO) can act as electrodes in a novel aqueous Li ion battery that exhibits outstanding capacity retention during prolonged cycling. Such an attractive property is related to the stability of both spinels (especially LNMO) under the typical working conditions of the cell.
