Rapid Microwave Synthesis of β-SnWO4 Nanoparticles: An Efficient Anode Material for Lithium Ion Batteries

We report a facile synthesis of β-SnWO4 nanoparticles via microwave heat treatment using SnCl2 and H2WO4 in the presence tamarind seed powder. An X-ray diffraction analysis confirmed crystalline nature revealing cubic structure nanoparticles. The morphological features were visualized scanning electron microscope that exhibited homogenously distributed clusters nanoparticles, which further transmission microscope. micrographs also displayed some porosity. Energy dispersive spectroscopy elemental contents such as tin, oxygen tungsten same stoichiometric ratio expected by respective empirical formula. A high-resolution was used to find d-spacing, ultimately analyze structural parameters. spectrum obtained Fourier transform infrared illuminated different stretching vibrations. Additionally, Barrett–Joyner–Halenda carried out investigate N2 adsorption-desorption isotherm well govern pore size distribution. Cyclic voltammetry measurements implemented ongoing electrode reactions throughout charge/discharge for nanostructures. galvanometric curves are discussed. high specific capacitance (600 mAhg–1 at 0.1 C) excellent columbic efficiency (~100%) achieved.
