Abstract
Official abstract text for this publication.
A method of manufacturing a composite electrode for an all-solid-state battery includes: preparing a precursor solution by mixing at least one solid electrolyte precursor and at least one polar solvent; stirring the precursor solution; preparing an electrode slurry by adding an active material to the stirred precursor solution; and heat-treating the electrode slurry and obtaining the composite electrode for the all-solid-state battery, wherein the composite electrode for the all-solid-state battery includes: the active material; and a coating layer disposed on the active material and including a solid electrolyte.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite electrode for an all-solid-state battery, the composite electrode comprising: an active material; a coating layer disposed on the active material, and including a solid electrolyte and an amorphous solid electrolyte, wherein an amount of the amorphous solid electrolyte is greater than 50 wt % and less than or equal to 80 wt % based on a total of 100 wt % of the coating layer. 2. The composite electrode of claim 1 , wherein the solid electrolyte comprises PS 4 3- . 3. The composite electrode of claim 1 , wherein the solid electrolyte comprises at least one selected from a group consisting of Li 3 PS 4 , Li 6 PS 5 Cl, Li 6 PS 5 ClBr, Li 6 PS 5 Br, and a mixture thereof. 4. The composite electrode of claim 1 , wherein the coating layer has a thickness of 200 nm or less. 5. The composite electrode of claim 1 , wherein the coating layer has a Young's modulus of 18 to 30 GPa.
