Abstract
A novel polyelectrolyte gel system, promising for application in secondary polymer lithium batteries, is presented. The gel is a copolymer of N,N-dimethylacryl amide and lithium 2-acrylamido-2-methyl-1-propane sulphonate, chemically cross-linked to form a three-dimensional network. The gel was polymerised in a solvent mixture of N,N-dimethylacetamide and ethylene carbonate. The electrochemical stability of the system was examined. The effects of the monomer composition, polyelectrolyte concentration and temperature on the ionic conductivity were studied and are discussed.
