Single crystalline rhombus-shaped Na0.7MnO2 nanoplates have been synthesized by a hydrothermal method. 0.7MnO2 single crystals predominantly exposed their (100) crystal plane, which is active for Na+-ion insertion and extraction. When applied as cathode materials for sodium-ion batteries, Na0.7MnO2 nanoplates exhibited a high reversible capacity of 163mAhg(-1), a satisfactory cyclability, and a high rate performance. (+)-ion insertion/extraction during the discharge and charge process.
