Abstract
The present disclosure relates to a composite solid electrolyte for a lithium secondary battery and a preparation method thereof.
Claims18
A method for preparing a composite solid electrolyte for a lithium secondary battery, comprising the steps of:
- (S1) preparing a first composite by forming a hydrogel of a first polymer from a solution including the first polymer having a cross-linkable functional group in its (side chain) and a ceramic compound;
- (S2) preparing a ceramic ion conductor by sintering the first composite;
- and
- (S3) preparing a second composite by immersing the ceramic ion conductor in a solution including a second polymer and a lithium salt and drying it.
