Double-Shelled CoMn2O4 Hollow Microcubes as High-Capacity Anodes for Lithium-Ion Batteries



Novel double-shelled CoMn2O4 hollow microcubes with nanometer-sized building blocks have been prepared by a facile co-precipitation and annealing method. In virtue of the unique structural features, the resultant CoMn2O4 hollow structures exhibit high specific capacity (∼830 mA h g−1 at 200 mA g−1) and good cycling performance as an anode material for lithium-ion batteries.
