Enhanced Electrochemical Performances of Porous MnO as Anode material for Lithium Ion Batteries Prepared by Magnetic Field Assisted Hydrothermal Method

Porous MnO prismoid was prepared by the magnetic-field assisted hydrothermal method. Influences of magnetic field (H = 2T) on microstructure, morphology, and electrochemical properties were studied. Under the action of magnetic field, X-ray diffraction results indicate that the crystal structure of MnO microprism is in accord with that of MnO microcube. SEM and TEM images suggest that the average grain size of MnO microprism decreases slightly. The electrochemical measurements show that MnO prismoid represents better than MnO microcube as the anode material for Lithium-ion batteries, which can be explained by the fact of modified crystal structure under the assistance of magnetic field.
