Potassium phosphotungstate spheres as an anode material for a solar rechargeable battery

Author affiliations

Abstract

Potassium phosphotungstate spheres, prepared by a simple coprecipitation method, are introduced for the first time as an anode material for a solar rechargeable battery. The microstructure of the as-prepared potassium phosphotungstate spheres is characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results show that the obtained potassium phosphotungstate particles were monodisperse and uniform spheres and present good photo-generated electron storage capacity with suitable redox potentials. Correspondingly, the as-fabricated battery using potassium phosphotungstate as the anode material exhibits satisfactory solar energy conversion and storage as well as rechargeable capability. Therefore, the potassium phosphotungstate spheres can be used as potential anode material for applications in the solar rechargeable battery.
