High interfacial lithium storage capability of hollow porous Mn2O3 nanostructures obtained from carbonate precursors

The preparation of porous Mn2O3 boxes has been developed via a carbonate precursor route. As a Li-ion battery anode, it delivers a high reversible capacity of 1442 mA h g(-1) over 600 cycles at 800 mA g(-1), and 65% of the capacity originates from the gradually emerging interfacial storage contribution.
