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 electrolytes, are here reported and discussed. The electrolytes have a very high ionic conductivity, an acceptable lithium ion transport number, and a wide electrochemical stability window. The members of the family which appear most promising in terms of stability of the lithium electrode interface have been tested as electrolyte separators in high voltage, thin layer, laminated rechargeable batteries. Preliminary results provided indications of promising performance in terms of voltage output and cyclability.
