Claims15
A solid electrolyte comprising:
- a covalent organic framework containing a repeating unit represented by the following Chemical Formula 1;
- and a crosslinked polymer derived from a crosslinkable monomer.
- In Chemical Formula 1, A is a mono- or polycyclic ring compound,
- —X— is a divalent linking group, and
- R1 to R4 are independently selected from —H, —COOM, —SM, —SO2M, —SO3M, —PO3M, or —PO4M, where R1 to R4 are not simultaneously —H, and M is Li, Li2, or Li3.
A method for manufacturing a solid electrolyte, comprising the steps of:
- (S1) applying pressure to a slurry composition for manufacturing a solid electrolyte, the composition comprising (i) a covalent organic framework containing a repeating unit represented by the following Chemical Formula 1 and (ii) a crosslinkable monomer selected from the group consisting of a polyalkylene oxide-based polyfunctional monomer, 11-azido-3,6,9-trioxaundecan-1-amine, acrylonitrile, methacrylamide, and a combination of two or more thereof;
- and
- (S2) manufacturing a crosslinked polymer by polymerizing the solid electrolyte slurry composition.
