The pristine ZnWO₄ and ZnWO₄/SnO₂ composite was synthesized by solvothermal method. The crystal structure of the ZnWO₄ and ZnWO₄/SnO₂ composite is determined by powder X-ray diffraction (XRD) pattern. The morphology of the samples investigated using SEM and found to be agglomerated structure. The samples are tested as an electrode material for supercapacitor using electrochemical techniques like cyclic Voltammetry (CV), Galvanostatic Charge-Discharge (GCD) and Electrochemical Impedance Spectroscopy (EIS). The ZnWO₄/SnO₂ composite reveals 56.7 F/g specific capacitance at 1 mV/s scan rate which is higher than that of pristine material and also ZnWO₄/SnO₂ composite exhibits good cyclic stability than pure ZnWO₄.

采用溶剂热法合成了原始的ZnWO ₄和ZnWO ₄ / SnO ₂复合材料。ZnWO ₄和ZnWO ₄ / SnO ₂复合材料的晶体结构通过粉末X射线衍射（XRD）图案确定。使用SEM研究样品的形态，发现其为团聚结构。使用电化学技术，例如循环伏安法（CV），恒电流充放电（GCD）和电化学阻抗谱（EIS），将样品作为超级电容器的电极材料进行测试。ZnWO ₄ / SnO ₂该复合材料在1 mV / s的扫描速率下具有56.7 F / g的比电容，高于原始材料，并且ZnWO ₄ / SnO ₂复合材料的循环稳定性优于纯ZnWO ₄。
