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

A method of manufacturing an all-solid-state battery, the method comprising:

• forming a first electrode member by forming first active material layers on both surfaces of a first current collector, wherein the first electrode member has a larger length than width;
• 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, wherein the second electrode member has a larger length than width;
• 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, wherein a first longitudinal end of the pressed second electrode member coincides with a first longitudinal end of the pressed first electrode member and a second longitudinal end of the pressed second electrode member protrudes a predetermined distance farther than a second longitudinal end of the pressed first electrode member;
• and
• pressing the laminated body by passing the laminated body between a pair of rollers to form a pressed laminated body..

A method of manufacturing an all-solid-state battery, the method comprising:

• 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, wherein the pressed first electrode member has a thickness of 80 to 90% of a thickness of the first electrode member before the pressing;
• 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, wherein the pressed second electrode member has a thickness of 80 to 90% of a thickness of the second electrode member before the pressing;
• 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.
