Abstract
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.

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;
- 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 forming of the second electrode member occurs before any pressing of the second electrode member;
- 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.
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, wherein the forming of the second electrode member occurs before any pressing of the second electrode member;
- 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.
