AbstractA novel facile construction of nanoscale laminated Na3V2(PO4)(3) for a high-performance sodium ion battery (SIB) cathode is proposed. In the synthesis process, a crystallized intermediate precursor with low-cost raw materials is prepared by introducing a high temperature molten-state NH3 thermal-reduction process, which acts as a reaction template to control the crystal growth and the final morphology of Na3V2(PO4)(3). The assynthesized nanoscale laminated Na3V2(PO4)(3) possesses continuous Na+/electron pathways, large electrode/electrolyte contact area and sufficient carbon coating, resulting in fast Na+ extraction/insertion and electron transport during the electrochemical reaction process, which is shown to achieve excellent rate capability and decent cycling stability. At a low rate of 0.5C, the discharge specific capacity is approximately 117 mA h g(-1), which is very close to its theoretical specific capacity, and there is only a very minor capacity fade after continuous 250 cycles at 2C. Even at 50C, the discharge specific capacity is as high as 80 mA h g(-1) and the reversible capacity retention after 3000 cycles remains more than 78%. In addition, the X-NVP cathode shows stable cycling performance and acceptable rate performance with a reversible capacity of 110 mA h g(-1) at 0.2C at a low temperature of -20 degrees C, which has rarely been reported previously in the SIB field. The intermediate precursor prepared by the high temperature moltenstate thermal-reduction method, acting as the reaction template of the final product, provides a facile and economic solution for the synthesis of high-performance SIB cathode materials.
