Electrochemical behaviour of temperature-based bismuth phosphate nanostructures for energy storage application

Abstract

The current study described a simple and quick synthesis procedure of BiPO4nanostructuresat varioustemperatures. According to XRD and Raman spectroscopy, the produced samples contain a hexagonal phase with no impurity. A field emission scanning electron microscope (FESEM) was used to identify the development of non-uniform rectangular and hexagonal nanoparticles. The electrochemical properties of the fabricated electrodes were examined usingGalvanostatic charge-discharge (GCD), Cyclic Voltammetry (CV), and Electrochemical Impedance Spectroscopy (EIS). The BP140 electrode showed the specific capacity of 497 Cg−1at 2 Ag−1and better cycle constancy, i.e., 71 percent at 30 Ag−1over 5000 cycles.
