Claims20
A glass-polymer composite electrolyte comprising:
- a glass electrolyte comprising at least one lithium compound and at least one compound selected from the group consisting of P.sub.2 S.sub.5, SiS.sub.2 and GeS.sub.2 ;
- and
- a polymer electrolyte comprising a lithium salt.
A method of preparing a glass-polymer composite electrolyte comprising:
- heating a mixture of at least one lithium compound and at least one compound selected from the group consisting of P.sub.2 S.sub.5, SiS.sub.2 and GeS.sub.2 at 700 to 900.degree. C.;
- forming a glass electrolyte by cooling the mixture;
- mixing the glass electrolyte with a polymer electrolyte comprising a lithium salt to produce a composite electrolyte;
- and
- shaping by compressing the composite electrolyte at 60 to 100.degree. C.
