Abstract
A method of manufacturing a positive electrode for sulfide-based all-solid-state batteries, including: preparing a slurry, coating the slurry on a current collector, and then drying. The slurry is prepared by a method including the steps of a) mixing a positive electrode active material and a solid electrolyte in a dry state; b) adding a conducting agent to the mixture of step a) and mixing in a dry state; and c) adding a binder and a solvent to the mixture of step b) and mixing in a wet state.
