1. A roll-to-roll formation method of a solid electrolyte using metal colloidal particles, the roll-to-roll formation method comprising:
(a) directly coating a metal electrode foil with the metal colloidal particles to form a solid electrolyte layer; and
(b) supplying a sulfur source to the solid electrolyte layer formed in step (a) to induce sulfidation reaction, thereby forming a sulfide-based solid electrolyte layer.
