AbstractMn2O3 is a promising anode material for lithium ion battery. Two different kinds of structures of Mn2O3 were synthesized via solution processes, the Mn2O3 porous cubes and hollow spheres. Scanning electron microscope images and transmission electron microscopy images clearly show the structures. Electrochemical impedance spectroscopy and cyclic voltammetry measurements were used to characterize their electrochemical properties. As anode materials for lithium ion batteries, Mn2O3 porous cubes performed similarly as Mn2O3 hollow spheres. Both samples started with high initial capacities (1583.2 mAh/g and 1550.7 mAh/g) which were reduced to 173.3 mAh/g and 162.0 mAh/g at 100th cycle at a current density of 100 mA/g. The decrease is likely due to morphology destruction the materials in charging and discharging process.
