Facile Synthesis of Porous Mn2O3 Nanoplates and Their Electrochemical Behavior as Anode Materials for Lithium Ion Batteries

Porous Mn2O3 nanoplates were prepared by a facile polyol solution method combined with a simple post-annealing process. The porous Mn2O3 nanoplates were characterized by XRD, field-emission SEM, high-resolution TEM, and N-2 adsorption/desorption isotherm measurements. The formation process for the Mn2O3 nanoplates was proposed as a morphology-conserved transformation strategy. These porous nanoplates exhibited improved electrochemical performance with excellent cycling stability and good rate capability when applied as anode materials in lithium ion batteries.
