Investigations on electrical, electrochemical, and thermal properties of gelatine-based novel biopolymer electrolytes for energy storage applications
Economical and environmentally friendly natural polymer electrolytes are prepared using a combination of gelatine, polyvinyl alcohol (PVA), and magnesium chloride (MgCl2) by solution casting technique. These electrolytes exhibit enhanced amorphous properties confirmed by X-ray diffraction (XRD). The homogeneous surface is confirmed by scanning electron microscopy (SEM), and the elemental composition is confirmed by energy-dispersive X-ray (EDX) spectroscopy. The thermal stability of the biopolymer electrolytes is determined between 0 and 350 °C by thermal gravimetry analysis (TGA). Electrochemical impedance spectroscopy (EIS) confirms the higher ionic conductivity of 4.1 × 10−3 S/cm for Gelatine:PVA:MgCl2 (0.5 g:0.5 g:0.4 g) electrolyte at normal temperature. The cyclic voltammetry (CV) curve reveals the non-faradaic behavior of electrolytes. The specific capacitance records 23.9 F/g at 10 mV/s scan rate and drops to 7.1 F/g at 150 mV/s, a higher scan rate. For the higher conducting material, linear sweep voltammetry (LSV) analysis reveals a potential window of − 1.2 to + 1 V. According to the research, this solid polymer electrolyte may be a good choice for electrochemical devices because of their excellent electrochemical behavior. The objective of this research is to explore the potential of these solid polymer electrolytes for use in electrochemical devices, given their excellent electrochemical behavior. Future work will focus on optimizing the electrolyte composition and further enhancing their electrochemical performance for practical applications in energy storage devices.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
