Abstract

This paper reports the successful fabrications of polymer electrolytes using biopolymer pectin in conjunction with ammonium azide (NaN₃) salt by solution casting method. The ionic conductivity of these electrolytes was evaluated using EIS at room temperature. Among the compositions tested, the highest conductivity of 2.3 × 10⁻³ S cm⁻¹ was observed to sample of 5 wt.% of NaN₃. The charge carriers' concentration (n) and mobility (µ) were calculated to understand the conductivity behavior attributed to dispersoids. For the calculation of n and μ, two theoretical models were used, namely the Trukhan and the S&G Model. The correlations between conductivity, n and μ are discussed.

果胶基生物聚合物电解质的导电性：寻找理论框架

本文报告了利用生物聚合物果胶和叠氮化铵（NaN3）盐通过溶液浇铸法成功制备聚合物电解质的情况。这些电解质的离子电导率在室温下通过 EIS 进行了评估。在测试的成分中，NaN3 含量为 5 wt.% 的样品电导率最高，达到 2.3 × 10-3 S cm-1。通过计算电荷载流子浓度（n）和迁移率（μ），可以了解分散体的导电行为。在计算 n 和 μ 时，使用了两种理论模型，即 Trukhan 模型和 S&G 模型。讨论了电导率、n 和 μ 之间的相关性。

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
