Abstract
Official abstract text for this publication.
Provided are: a solid battery which has been sealed in an exterior material under a reduced pressure, wherein gas in the exterior material can be fully removed when depressurizing the inside of the exterior material; and a method of manufacturing the solid battery, the solid battery having a single cell having: a laminated body having a cathode layer, an anode layer, and an electrolyte layer disposed between the cathode layer and the anode layer; an insulating part disposed on an outer perimeter of the laminated body in a cross-sectional view of the laminated body in a direction orthogonal to a lamination direction thereof, and a pair of current collectors sandwiching the laminated body and the insulating part, wherein the single cell has been sealed in an exterior material under a reduced pressure; and the insulating part has vent holes.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a solid battery comprising the steps of: making a single cell comprising: a laminated body having a cathode layer, an anode layer, and an electrolyte layer disposed between the cathode layer and the anode layer; at least one insulating layer having vent holes formed of a sequence of bubbles and having a characteristic of allowing gas to pass through, the at least one insulating layer being disposed on an outer perimeter of the laminated body in a cross-sectional view of the laminated body in a direction orthogonal to a lamination direction thereof; and a pair of current collectors sandwiching the laminated body and the at least one insulating layer; sealing an exterior material that accommodates the single cell, an inside of the exterior material being under a reduced pressure; and after sealing the exterior material, pressurizing and/or heating the at least one insulating layer such that the vent holes are closed up and lose the characteristic of allowing gas to pass through, and the vent holes become evidence that vent holes used to exist.
