Abstract
The present invention relates to a polymer electrolyte and a method for manufacturing same. More specifically, a polymer electrolyte with improved ion conductivity can be produced by adding boron nitride to a solid electrolyte comprising polysiloxane.
Claims18
A solid electrolyte comprising:
- a polysiloxane;
- and
- boron nitride (BN),
- wherein the boron nitride is a boron nitride surface-modified with polycyclic aromatic hydrocarbon.
1 more element
A method for preparing a solid electrolyte comprising the steps of:
- (S1) reacting a boron nitride with a polycyclic aromatic hydrocarbon to form a surface-modified boron nitride;
- (S2) dissolving a polysiloxane, a crosslinking agent and a photo-initiator in an organic solvent to form a mixed solution;
- (S3) adding the surface-modified boron nitride and a lithium salt to the mixed solution to form a slurry;
- and
- (S4) casting the slurry onto a substrate and then curing the slurry.
