Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The method of claim 1 , wherein pressing the first electrode member comprises applying a pressure so that the pressed first electrode member has a thickness of 80 to 90% of a thickness of the first electrode member before the pressing. 3 . The method of claim 1 , wherein pressing the first electrode member comprises passing the first electrode member between the pair of rollers. 4 . The method of claim 1 , wherein pressing the second electrode member comprises applying a pressure so that the pressed second electrode member has a thickness of 80 to 90% of a thickness of the second electrode member before the pressing. 5 . The method of claim 1 , wherein pressing the second electrode member comprises passing the second electrode member between the pair of rollers. 6 . The method of claim 1 , wherein the pressed laminated body has a thickness of 100 to 300 μm. 7 . The method of claim 1 , wherein the first electrode member has a larger length than width. 8 . The method of claim 1 , wherein the second electrode member has a larger length than width. 9 . The method of claim 1 , 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. 10 . 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. 11 . The method of claim 10 , wherein: pressing the first electrode member comprises passing the first electrode member between the pair of rollers; and pressing the second electrode member comprises passing the second electrode member between the pair of rollers.
