Abstract:

Single crystalline rhombus-shaped Na0.7MnO2 nanoplates have been synthesized by a hydrothermal method. TEM and HRTEM analyses revealed that the Na0.7MnO2 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 163 mA h g-1, a satisfactory cyclability, and a high rate performance. The enhanced electrochemical performance could be ascribed to the predominantly exposed active (100) facet, which could facilitate fast Na+-ion insertion/extraction during the discharge and charge process. © 2013 Wiley-VCH Verlag GmbH & Co.
