“…Similar current humps could be perceived from all of the current cycles. During lithiation, three peaks could be depicted specifying a multi-lithiation progression [21]. The reduction of β-SnWO4 to Sn and W was noticed from the first reduction peak and appeared around 2.31 V as prescribed in Equation (9).…”

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

The strategy of crystal structure transformation tunes the electrochemical properties favoring the energy storage performance of the electrode material. Herein, we prepared SnWO4 nanoflakes through Sn incorporation into the tungsten oxide matrix by a single-step wet chemical method. The crystal structure tuning occurs from the orthorhombic structure of hydrated tungsten oxide (WO3·H2O, i.e., HWO) to the hexagonal (SnWO4, i.e., SWO) structure. Simultaneously, the morphology tailoring from nanodisks of HWO to nanoflakes of SWO is realized as a result of the Sn ion exchange mechanism. Further, the electrochemical supercapacitor of SWO nanoflakes demonstrates almost 2-fold enhancement in the specific capacitance of 622 F g–1 at 0.5 A g–1 over HWO nanodisks (255 F g–1). Moreover, the asymmetric supercapacitor (ASC) of SWO//activated carbon (AC) exhibits the specific capacitance of 50 F g–1 at 1 A g–1, with the maximum energy density and power density of 18 Wh kg–1 and 7000 W kg–1, respectively. Furthermore, superior performance of the aqueous zinc-ion battery (AZIB) demonstrates the specific capacity of 75 mA h g–1 at 0.3 A g–1 along with 106% stability and 101% coulombic efficiency after 70 cycles. The improved performance of SWO nanoflakes in the pseudocapacitor and AZIB is attributed to crystal structure tuning, increasing conductivity, enhanced surface area, and Sn redox sites. Therefore, the SWO nanoflakes are favorable cathode materials for commercial energy storage devices.
