Abstract:
Polymer-based solid electrolytes have a potential electrochemical application in energy conversion and storage devices. In this investigation, polyurethane and its solid polymer electrolytes were prepared by an eco-friendly cost-effective method using vegetable oils. The neem oil-based polyurethane (PU) was prepared by polycondensation method. The polyurethane and the corresponding solid polymer electrolyte (SPE) were characterized by FT-IR, 1H NMR, GPC, XRD, SEM, TEM. The conductivity of PU/PVP-xLiClO4 was measured using electrochemical impedance spectroscopy. The ionic conductivity of the SEPs with different LiClO4 composition shows a higher value for 15% LiClO4 composition. The thermal analysis was carried out study the stability of the prepared PU and its SPEs. The Stability constant for PU was higher than the composite due to the segmental motion in the PU
