Facile synthesis of Li2MnO3 nanowires for lithium-ion battery cathodes

Abstract

In the present work, Li₂MnO₃ nanowires with a good electrochemical performance were synthesized by a simple molten-salt method, at a low temperature, using Mn₂O₃ nanowires with MnF₂ as the Mn source. The discharge capacity of the Li₂MnO₃ nanowires used as the cathode material in a lithium-ion battery was up to 159.8 mA h g⁻¹ after 27 cycles in a voltage range of 2.0 to 4.8 V at a current density of 20 mA g⁻¹ at room temperature. They also displayed a good cycling stability and rate performance at different current densities.
