ELECTROCHEMICAL CHARACTERIZATION OF NEW CONDUCTING POLYMER ELECTROLYTES

Prepared with bis-amino PEO/PPO copolymers, with and without amino PEO oligomers, and the cross-linking agent butanediol diglycidyl ether, a new series of cross-linked polymer electrolytes were investigated for their ionic conductivity and for the electrochemical properties of li thium cycleability and lithium polymer electrolyte compatibility. Room -temperature conductivity was found to be two order of magnitude highe r than that of 'conventional' PEO-based electrol tes; compatibility wi th metallic lithium proved to be fairly good.
