ROLL-TO-ROLL FORMATION METHOD FOR SOLID ELECTROLYTE USING METAL COLLOIDAL PARTICLES

The present invention relates to a roll-to-roll formation method for a solid electrolyte using metal colloidal particles and, more specifically, to a roll-to-roll formation method for a solid electrolyte using metal colloidal particles, wherein the method enables design of a solid electrolyte material with a desired composition by means of direct coating of metal colloidal particles on a metal electrode foil, and enables formation of a void-free sulfide-based solid electrolyte material by sequentially inducing, on a solid electrolyte forming layer, a sulfurization reaction by a roll-to-roll method without a complicated powder processing process.
