Method of Manufacturing All-Solid-State Battery Using Roll Press Process

An embodiment method of manufacturing an all-solid-state battery includes forming a first electrode member by forming first active material layers on both surfaces of a first current collector, pressing the first electrode member to form a pressed first electrode member, forming a second electrode member by forming second active material layers on both surfaces of a second current collector and forming solid electrolyte layers on the second active material layers, pressing the second electrode member to form a pressed second electrode member, forming a laminated body by layering the pressed first electrode member and the pressed second electrode member, and pressing the laminated body by passing the laminated body between a pair of rollers to form a pressed laminated body.
