摘要：
A biopolymer electrolyte consisting of iota-carrageenan (I-Carrageenan) and LiCl is prepared using solution casting method. XRD analysis confirms the enhancement in amorphous nature of the prepared polymer electrolytes due to the incorporation of LiCl. Fourier transform infrared (FTIR) spectroscopy is used to analyze the complexation of electrolytes. Electrochemical impedance spectroscopy is utilized to find the ac electrical conductivity of the electrolytes. The combination of 1.0 g I-Carrageenan and 0.3 g LiCl displays highest ionic conductivity value of 5.33 × 10−3 S cm−1 at room temperature. Transference number measurements indicate that the conductivity process is predominantly by Li+ ions. Lithium ion conducting battery is constructed with the highest conducting polymer electrolyte, and its discharge performance is analyzed.
