Relationship Between the Concentration of Dopant and the Properties of Ion Transport in Plasticized NaCMC-Pectin Polyblend Electrolyte Membranes
Original language description
Due to the rapid evolution of modern technologies such as portable electronic devices, electric vehicles, and large-scale power sources, there is a growing imperative to develop low-cost and eco-friendly energy storage devices (ESDs). To date, there hasn't been a comprehensive examination specifically focused on biopolymer-based electrolytes for flexible energy storage and conversion devices. This research investigates the structural and electrical characteristics of sodium carboxymethyl cellulose (NaCMC)–pectin (PC)–glycerol–NH4Br electrolyte films and explores their potential uses in proton batteries. Films of plasticized solid polymer electrolyte (SPEs) were produced using the solution casting method. Fourier-transform infrared (FTIR) analysis confirmed the interaction between the salt and polymer blends. X-ray diffraction (XRD) results indicated that the inclusion of various salt concentrations (up to 25 wt%) enhanced the amorphous phase of the polymer blend. Similarly, EIS revealed that the sample containing the highest salt concentration (25 wt. %) showed the highest ionic conductivity measured at 4.68 × 10−4 S cm−1. According to LSV analysis, this sample demonstrated the capability to operate safely within a voltage limit of 2.4 V. This electrolyte was utilized to create a proton battery for energy storage purposes.
