Investigation of the exceptional charge performance of the 0.93Li4−xMn2O5–0.07Li2O composite cathode for Li-ion batteries

Herein, we report a detailed study on the high-energy density nanostructured Li_4−xMn₂O₅–Li₂O composite with a high discharge capacity of 355 mA h g⁻¹, constituting the highest value reported to date for a lithium–manganese oxide electrode.
