Abstract
The present invention relates to a solid polymer electrolyte in the form of an organic-organic composite material, intended to be used in a lithium-polymer battery. The invention also relates to a process for manufacturing such an electrolyte. This electrolyte is notably intended for making a lithium-polymer battery or an “all-solid” battery, notably as regards the ion-conducting separator. The invention thus also relates to a battery separator comprising such a polymer electrolyte, to processes for manufacturing same and to the battery incorporating this electrolyte.
Claims17
A solid polymer electrolyte for a battery operating at a temperature below 60° C., said electrolyte comprising:
- a thermoplastic polymer in the form of a porous film, said polymer having a molecular mass of greater than 50,000 g/mol,
- an oligomer impregnating said thermoplastic polymer film, this oligomer being an ion conductor, and
- one or more lithium salts.
