The Guar gum (GG)–lithium bis(trifluoromethanesulphonyl)imide (LiTFSI)-glycerol-based solid biopolymer electrolyte has been investigated. The polymer electrolytes has been prepared via solution casting technique and characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), 3D-laser profilometry and AC impedance studies. The amorphous nature and complexation has been revealed by XRD and FTIR. TGA reveals that the polymer electrolyte is stable up to 260°C. The average roughness was measured using 3D-laser profilometry. The ionic conductivity of the electrolyte was studied using impedance analysis. The best optimum ionic conductivity of 2.041 × 10 −3 S cm −1 has been achieved for the film containing 60 wt% GG–40 wt% LiTFSI.

甘油增塑的双（三氟甲磺酰基）亚胺锂（LiTFSI）掺杂的瓜尔胶基固体生物聚合物电解质的制备和表征

已经研究了瓜尔胶（GG）-双（三氟甲磺酰基）亚胺锂（LiTFSI）-甘油基固体生物聚合物电解质。聚合物电解质已通过溶液浇铸技术制备，并通过傅里叶变换红外 (FTIR)、X 射线衍射 (XRD)、热重分析 (TGA)、3D 激光轮廓仪和交流阻抗研究进行表征。XRD 和 FTIR 揭示了无定形性质和络合。TGA 表明聚合物电解质在高达 260°C 时是稳定的。使用 3D 激光轮廓仪测量平均粗糙度。使用阻抗分析来研究电解质的离子电导率。对于含有 60 wt% GG–40 wt% LiTFSI 的薄膜，已经实现了 2.041 × 10 -3 S cm -1 的最佳最佳离子电导率。
