Lithium polymeric membrane based on a semi-crystalline fluorinated polymeric matrix and a non-ionic surfactant

摘要

Lithium polymeric membrane characterized in that it comprises a fluorinated and semi-crystalline polymeric matrix, a lithium salt and a non-ionic surfactant as a plasticizer. Preferably, it comprises poly(vinyliden fluoride-co-hexafluoropropylene), polyethylene glycol tert-octylphenyl ether and lithium hexafluorophosphate. It also comprises the use of this polymeric membrane as an electrolyte and/or electrical insulator in lithium polymeric batteries.
