Abstract
The present disclosure relates to a thermoplastic polyurethane (TPU) based polymer electrolyte composition hosting an ion conductive salt in the presence of a plasticizer.
Claims17
A thermoplastic polyurethane (TPU) based polymeric electrolyte composition comprising an ion conductive salt in the presence of a plasticizer which when made into a film has a peel strength to glass comprising between 3-25 N/mm as measured according to ASTM D 3167,
- wherein the composition comprises hard and soft segments,
- wherein the hard segment contains an aliphatic isocyanate-containing compound and a chain extender, and
- wherein a molar ratio between the aliphatic isocyanate-containing compound and the chain extender is from 1 to 1.5.
A method for making a TPU-based polymeric electrolyte composition comprising an ion conductive salt which when made into a film has a peel strength to glass comprising between 3-25 N/mm as measured according to ASTM D 3167, wherein the method comprises:
- mixing an aliphatic isocyanate-reactive compound with a chain extender to form a mixture, wherein a molar ratio between the aliphatic isocyanate-containing compound and the chain extender is from 1 to 1.5;
- dissolving an ion conductive salt in a plasticizer to form a plasticizer loaded with the salt;
- mixing the plasticizer loaded with the salt with the mixture to form an isocyanate-reactive mixture;
- and
- adding the isocyanate-reactive mixture to an isocyanate-containing compound and forming the TPU-based polymeric electrolyte composition.
