Abstract: | The present paper describes a novel synthesis of organic polymer gel electrolyte for Li-ion cell, comprising of Polyethylene oxide (PEO), LiClO4, LiOH, Li2SO4 and dimethyl formamide (DMF). The gel was obtained with a specific weight ratio of these components after appropriate heat treatment. The gel when layered over graphite plate and LiCoO2 cathode, it forms laboratory model Li-ion cell. The cell shows an OCP value of 3.624 V at 298 K.The galvanostatic charge/discharge tests show performances comparable to liquid electrolyte system. |
