A NEW CLASS OF ADVANCED POLYMER ELECTROLYTES AND THEIR RELEVANCE IN PLASTIC-LIKE, RECHARGEABLE LITHIUM BATTERIES

The synthesis, properties, and application of a new class of polymer e lectrolytes are here reported and discussed. The electrolytes have a v ery high ionic conductivity, an acceptable lithium ion transport numbe r, and a wide electrochemical stability window. The members of the fam ily which appear most promising in terms of stability of the lithium e lectrode interface have been tested as electrolyte separators in high voltage, thin layer, laminated rechargeable batteries. Preliminary res ults provided indications of promising performance in terms of voltage output and cyclability.
