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 ofmagnetic 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 MnOmicroprism is in accord with that of MnO microcube. SEM and TEM images suggest that the averagegrain size of MnO microprism decreases slightly. The electrochemical measurements show that MnOprismoid represents better than MnO microcube as the anode material for Lithium-ion batteries, whichcan be explained by the fact of modified crystal structure under the assistance of magnetic field.
