摘要：
The present paper describes a novel synthesis of organic polymer gel electrolyte for Li-ion cell, comprising of Polyethylene oxide (PEO), LiC1O(4), 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. (c) 2005 Elsevier B.V. All rights reserved.
