Porous Mn 2 O 3 nanoplates were prepared by a facile polyol solution method combined with a simple post‐annealing process. The porous Mn 2 O 3 nanoplates were characterized by XRD, field‐emission SEM, high‐resolution TEM, and N 2 adsorption/desorption isotherm measurements. The formation process for the Mn 2 O 3 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.
