摘要

采用溶液浇铸法制备了不同CuCl2浓度(10、20、30 wt.%)的PVP和PVP/甘油聚合物电解质膜。采用FTIR、XRD、UV-Vis、DSC和TGA等技术对合成的电解质膜进行了表征。FTIR光谱显示PVP的O-H伸缩振动在3300 cm⁻1左右,在甘油和CuCl2的加入后,其强度变宽并减小。XRD分析显示,在2θ ~ 20°处有一个特征峰,随着CuCl2浓度的增加,峰向更高的角度移动,强度略有下降,表明基体的晶体结构被破坏。紫外-可见分析表明,纯PVP的光学带隙为3.6 eV,而在PVP/甘油体系中加入10%、20%和30%的CuCl2后,带隙分别显著降低至2.4、1.7和1.4 eV。DSC测量表明,玻璃化转变温度(Tg)分别从纯PVP的150°C降低到含有10%、20%和30% CuCl2的PVP/甘油复合材料的146、144和140°C。TGA结果表明,与纯PVP相比,CuCl2增强了PVP/甘油的热稳定性,在225°C下保持稳定。根据电导率测量,在室温下,含有20 wt.% CuCl2的体系的最高离子电导率为6.47 × 10⁻4 S/cm。实验数据表明,这些优化的电解质材料可能是高性能储能技术的合适候选者。

Investigating the structural, optical, and thermal behavior of CuCl2 incorporated PVP/glycerin-based polymer electrolytes for energy storage applications

Polymer electrolyte films composed of PVP and PVP/glycerin with varying concentrations of CuCl2 (10, 20, and 30 wt.%) were synthesized using the solution casting method. The synthesized electrolyte films were characterized using FTIR, XRD, UV–Vis, DSC, and TGA techniques. FTIR spectroscopy revealed an O–H stretching vibration of PVP around 3300 cm⁻1, which experienced broadening and a reduction in intensity upon the introduction of glycerin and CuCl2. XRD analysis displayed a characteristic peak at 2θ ~ 20°, with the peak shifting towards higher angles and a slight decrease in intensity as the CuCl2 concentration increased, indicating a disruption of the crystalline structure of the host matrix. UV–Vis analysis revealed that the optical bandgap of pure PVP was 3.6 eV, whereas the incorporation of 10, 20, and 30 wt.% CuCl2 into the PVP/glycerin system resulted in a significant reduction of the bandgap to 2.4, 1.7, and 1.4 eV, respectively. DSC measurements indicated a decrease in the glass transition temperature (Tg) from 150 °C for pure PVP to 146, 144, and 140 °C for the PVP/glycerin composites containing 10, 20, and 30% CuCl2, respectively. TGA results indicated enhanced thermal stability for PVP/glycerin with CuCl2, which remained stable up to 225 °C, compared to pure PVP. According to conductivity measurements, the highest ionic conductivity achieved for a system containing 20 wt.% CuCl2 is 6.47 × 10⁻4 S/cm at room temperature. The experimental data suggest that these optimized electrolyte materials could be suitable candidates for high-performance energy storage technologies.

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.
