摘要
固体聚合物电解质(SPE)因其在各种电化学设备中的应用而受到广泛研究。大多数固态聚合物电解质都由聚合物和盐组成,聚合物作为主材料可提供强度和良好的机械稳定性,而盐则可转移电荷载流子,从而提高导电性。利用电纺丝方法获得了基于聚(乙烯醇)(PVA)-聚(乙二醇)(PEG)共混物的纳米复合固体聚合物电解质膜,该膜与氯化锂和纳米填料 Al2O3 按不同的重量百分比比例复配。利用 X 射线衍射 (XRD) 和傅立叶变换红外光谱等多种实验方法对不同体系的电导率和结构特性进行了表征。在室温下,PVA-PEG-LiClO4-Al2O3(50-25-15-10)体系的最大离子电导率为 1.58 × 10-4 S cm-1,PVA-PEG 混合基质中的 LiClO4 盐的重量百分比为 15%。交流电导率报告表明,PVA-PEG-LiClO4-Al2O3 复合物的离子电导率受 LiClO4 浓度的影响。然而,纳米纤维聚合物电解质体系的电导率随着温度的升高而增加,在 353 K 时记录到最大电导率 1.58 × 10-2 S cm-1。
Studies of the Properties of New Electrospun Based on PVA-PEG Polymer Systems Electrolytes for Energy Storage Devices
Solid polymer electrolytes (SPEs) have been considerably investigated due to various electrochemical device applications. Most of the SPEs comprise polymer as a host material to provide strength and good mechanical stability and salt that transfers charge carriers to cause conductivity. Nanocomposite solid polymer electrolyte membranes based on poly(vinyl alcohol) (PVA)-poly(ethylene glycol) (PEG) blend complexed with LiClO4 and nanofillers Al2O3 at different weight percent ratios have been obtained by using electrospinning method. The conductivity and structural properties of the different systems have been characterized by using various experimental approaches such as X-ray diffraction (XRD) and Fourier transform infrared FTIR spectroscopy. The ionic conductivity of the systems has been measured by using an LCR meter in a temperature ranging from 298 to 353 K. Maximum ionic conductivity of 1.58 × 10-4 S cm-1 at room temperature has been observed for the system of PVA-PEG-LiClO4-Al2O3 (50-25-15-10) with 15 wt% weight percent of LiClO4 salt in PVA-PEG blend matrix. The ac conductivity report indicates that the ionic conductivity of the PVA-PEG-LiClO4-Al2O3 complex is influenced by the concentration of LiClO4. The effect of temperature on the ionic conductivity of polymer electrolyte complexes has been estimated by changing the temperature ranging from 298 to 353 K. However, the conductivity of the nanofiber polymer electrolyte systems increases with the rise of temperature, and the maximum conductivity of 1.58 × 10-2 S cm-1 has been recorded at 353 K. The temperature-dependent conductivity follows the Arrhenius behavior.
