Synthesis of single crystalline electro-conductive Na0.44MnO2 nanowires with high aspect ratio for the fast charge–discharge Li ion battery

We report the fast charge–discharge Li ion battery based on the nanostructural controlled Na 0.44 MnO 2 wires with high aspect ratio. The good fast charge–discharge property is observed because the single crystalline Na 0.44 MnO 2 nanowires have a high electronic conductivity as electrode active materials of lithium ion battery due to the one-dimensional single crystalline nanowire. Moreover, such nanosize structure could reduce the required lithium diffusion length in the active materials to the several tens of nanometer, also reduce the effective specific current density by high surface area, and increase the stability of cycle performance by the one-dimensional single crystalline structure.
