The present work reported a facile and fast microwave irradiation technique for the synthesis of BiPO4 nanornstructures at different microwave irradiation time (5, 10, & 15 min) with fixed power of 850 W. X-ray diffractionrnpattern (XRD), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy divulges that thernconsolidated samples have a hexagonal phase with no polluting influence. Field emission scanning electronrnmicroscope (FESEM) examination revealed the development of non-uniform hexagonal and rectangular-likerncrystals. A significant decrease in optical band energy (Eg) was observed with increasing the microwave irrarndiation time. The electrochemical properties of the as-developed sample studied by Cyclic voltammetry (CV),rnGalvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) in a three-electrodernarrangement with a 2 M KOH solution as an aqueous electrolyte. CV and GCD curve analysis demonstrate thernFaradaic battery-type redox behavior for all the BiPO4 electrode samples, unlike the carbon, deployed material.rnAs a battery-type behavior, the BP15 electrode exhibits excellent electrochemical performance with a significantrnific capacity (~610 C g-1), superb, remarkable cycling life (~97% at 2 A g-1 over 1000 cycles), respectivel
