Abstract
Lithium ion conducting polymer electrolytes based on triblock polymer P(VdCl-co-AN-co-MMA)–LiCl were prepared using a solution casting technique. XRD studies show that the amorphous nature of the polymer electrolyte has been increased due to the addition of LiCl. The maximum amorphous nature has been observed for 40 m% P(VdCl-co-AN-co-MMA)/60 m% LiCl samples. The FTIR study of the lithium ion conducting polymer membrane confirms the complex formation between the polymer P(VdCl-co-AN-co-MMA) and LiCl. The lithium ion conductivity is found to be 1.6 × 10−5 Scm−1 for the 40 m% P(VdCl-co-AN-co-MMA)/60 m% LiCl sample at room temperature. This value is found to be greater than that of pure polymer whose conductivity is found to be 1.5 × 10−8 Scm−1. To improve ionic conductivity, ethylene carbonate has been added as a plasticizer to the 40 m% P(VdCl-co-AN-co-MMA)/60 m% LiCl sample. When we add 0.6 m% of ethylene carbonate, it has been observed that the lithium ion conductivity has increased to 1.3 × 10−3 Scm−1. This value is two orders of magnitude greater than the 40 m% P(VdCl-co-AN-co-MMA)/60 m% LiCl sample. It is also observed from XRD patterns of 40 m% P(VdCl-co-AN-co-MMA)/60 m % LiCl/0.6 m % EC that the amorphous nature has been increased further. A dielectric study has been performed for the above membranes.
