Abstract

The electrochemical properties of a new hybrid electrode, liquid-polyoxometalate-polypyrrole (BMIM-PVMo₁₁-PPy) have been studied. The H₄[PVMo₁₁O₄₀] (PVMo₁₁) was combined with 1-Butyl-3-methyl-imidazolium (BMIM) ionic liquid and then doped on the polypyrrole (PPy) surface. In order to investigate the interaction between the BMIM, PVMo₁₁, and PPy compound was characterized using various analytical techniques, such as Infrared spectroscopy, thermal stability analysis, powder X-ray diffraction, multinuclear NMR (¹H and ¹³C), FESEM, EDX, and surface adsorption studies. The electrochemical performance of the BMIM-PVMo₁₁-PPy composite material has been tested in an aqueous 0.25 M H₂SO₄ electrolytic solution. The BMIM-PVMo₁₁-PPy composite exhibits the highest specific capacitance of 527.39 F g⁻¹ at a current density of 1 A g⁻¹, along with remarkable specific energy and power of 51.07 Wh kg⁻¹ and 1078.96 W kg⁻¹, respectively. The BMIM-PVMo₁₁-PPy composite was observed to light up red and blue color LED bulbs for 66 and 16 s, respectively, with 84 mg of sample coated on carbon cloth, suggesting an incredible specific power of that material.
