The present work reports the bismuth phosphate (BiPO₄) nanostructures, the next generation of perspective cathode material for energy storage device application prepared via using a simple microwave technique under prime conditions and at various microwave irradiation power rates (60%, 80%, and 100%) at a fixed temperature (100 $°C$). The formation of pure phase (hexagonal) of BiPO₄ nanostructures was revealed by XRD examination and verified by EDS studies, Raman, and FTIR spectra. FESEM analysis shows the formation of non-uniform rectangular-like crystals and the particle size distribution range∼ 41–52 nm. The electrochemical characterization of the as-prepared BiPO₄ cathode material was done using a CHI760E Electrochemical station in a three-electrode cell using a 2 M KOH aqueous electrolyte with Ag/AgCl as a reference electrode. The electrochemical analysis shows that at a current density of 2 A g^-1, the BP80 electrode exhibits a high value of specific capacity, i.e., 693 C g^-1 and 89% retention for 1200 cycles at 10 A g^-1. The results analysis revealed that microwave irradiation power rate plays a critical role in the electrochemical performance of BiPO₄ nanostructures.
