Abstract

Over the next phase of rechargeable batteries, a detailed investigation has gone into creating future cathode materials. The utilisation of phosphate framework materials as electrodes in the next source of energy storage technologies will be a challenging and appealing option and because of its best cycle and cycling rate, as well as its low cost. NaFePO4 has been regarded a viable electrode material in sodium ion batteries. Microwave, hydrothermal, and solid state procedures were used to synthesize the NaFePO4 nanoparticles. As per XRD structural studies, the solid state method shows the maximum intensity peaks of NaFePO4. Then the FTIR analysis was used to identify the PO4 3-groups and the morphology studies were done for the outcome of the solid state method. The findings demonstrated that the solid state produced NaFePO4 nanoparticles acts as a potential electrode materials for sodium ion batteries.
