Abstract
Official abstract text for this publication.
An all solid state battery including: a battery cell; a first current collecting member; a second current collecting member; and an outer package. The battery cell contains a sulfide solid electrolyte; the outer package includes a first outer package member arranged on a first surface side of the battery cell, and a second outer package member arranged on a second surface side of the battery cell; a resin layer A is arranged in, at least one position of, a position between the first outer package member and the first current collecting member, and a position between the second outer package member and the second current collecting member; a resin layer B is arranged in a side surface part of the battery cell; and each of the resin layer A and the resin layer B contains an adhesive resin.
First claim
Opening claim text (preview).
What is claimed is: 1 . An all solid state battery comprising: a battery cell; a first current collecting member arranged on a first surface of the battery cell; a second current collecting member arranged on a second surface of the battery cell, which is the surface opposes the first surface; and an outer package that protects the battery cell, the first current collecting member and the second current collecting member; wherein, a size of the all solid state battery is 4 cm 2 or less; the battery cell contains a sulfide solid electrolyte; the outer package includes a first outer package member arranged on the first surface side of the battery cell, and a second outer package member arranged on the second surface side of the battery cell; a resin layer A is arranged in, at least one position of, a position between the first outer package member and the first current collecting member, and a position between the second outer package member and the second current collecting member; a resin layer B is arranged in a side surface part of the battery cell; and each of the resin layer A and the resin layer B contains an adhesive resin. 2 . The all solid state battery according to claim 1 , wherein a resin layer A 1 is arranged as the resin layer A in the position between the first outer package member and the first current collecting member, and the resin layer A 1 is arranged so as to cover whole of the battery cell in a plan view along with a thickness direction. 3 . The all solid state battery according to claim 2 , wherein a resin layer A 2 is arranged as the resin layer A in the position between the second outer package member and the second current collecting member, and the resin layer A 2 is arranged so as to cover whole of the battery cell in a plan view along with a thickness direction. 4 . The all solid state battery according to claim 1 , wherein the resin B is arranged in an entire region from an edge of the first surface side to an edge of the second surface side in the side surface part. 5 . The all solid state battery according to claim 1 , wherein the resin layer B is arranged in entire surrounding of outer edge of the battery cell in a plan view along with a thickness direction. 6 . The all solid state battery according to claim 1 , wherein an area of the battery cell is 0.1 cm 2 or less.
