Abstract
Official abstract text for this publication.
A main object of the present disclosure is to provide an all solid state battery with excellent cycle characteristics. The present disclosure achieves the object by providing an all solid state battery comprising, in an order of, a cathode CA 1 , a first solid electrolyte layer, an anode AN, a second solid electrolyte layer, and a cathode CA 2 , along a thickness direction, wherein: the first solid electrolyte layer contains a first nonwoven fabric, and a first solid electrolyte arranged inside the first nonwoven fabric; the second solid electrolyte layer contains a second nonwoven fabric, and a second solid electrolyte arranged inside the second nonwoven fabric; and in a plan view along the thickness direction, an angle formed by a first fabric direction in the first nonwoven fabric and a second fabric direction in the second nonwoven fabric is 45° or more and 90° or less.
First claim

What is claimed is: 1 . An all-solid-state battery comprising, in an order of, a cathode CA 1 , a first solid electrolyte layer, an anode AN, a second solid electrolyte layer, and a cathode CA 2 , along a thickness direction, wherein: the first solid electrolyte layer contains a first nonwoven fabric, and a first solid electrolyte arranged inside the first nonwoven fabric; the second solid electrolyte layer contains a second nonwoven fabric, and a second solid electrolyte arranged inside the second nonwoven fabric; and in a plan view along the thickness direction, an angle formed by a first fabric direction in the first nonwoven fabric and a second fabric direction in the second nonwoven fabric is 45° or more and 90° or less. 2 . An all-solid-state battery comprising, in an order of, an anode AN 1 , a first solid electrolyte layer, a cathode CA, a second solid electrolyte layer, and an anode AN 2 , along a thickness direction, wherein: the first solid electrolyte layer contains a first nonwoven fabric, and a first solid electrolyte arranged inside the first nonwoven fabric; the second solid electrolyte layer contains a second nonwoven fabric, and a second solid electrolyte arranged inside the second nonwoven fabric; and in a plan view along the thickness direction, an angle formed by a first fabric direction in the first nonwoven fabric and a second fabric direction in the second nonwoven fabric is 45° or more and 90° or less. 3 . The all-solid-state battery according to claim 1 , wherein the angle is 80° or more and 90° or less. 4 . The all-solid-state battery according to claim 1 , wherein each of a void rate in the first nonwoven fabric and a void rate in the second nonwoven fabric is 70% or more and 90% or less. 5 . The all-solid-state battery according to claim 1 , wherein: in the first nonwoven fabric, a tensile strength of the first fabric direction is larger than a tensile strength of a direction orthogonal to the first fabric direction; and in the second nonwoven fabric, a tensile strength of the second fabric direction is larger than a tensile strength of a direction orthogonal to the second fabric direction. 6 . The all-solid-state battery according to claim 1 , wherein at least one of the first solid electrolyte and the second solid electrolyte is an inorganic solid electrolyte. 7 . The all-solid-state battery according to claim 6 , wherein the inorganic solid electrolyte is at least one kind of a sulfide solid electrolyte, an oxide solid electrolyte, and a hydride solid electrolyte. 8 . The all-solid-state battery according to claim 1 , wherein at least one of the first solid electrolyte and the second solid electrolyte is a molten salt, which is in a solid state at 25° C. 9 . The all-solid-state battery according to claim 1 , wherein at least one of the first solid electrolyte and the second solid electrolyte is a plastic crystal solid electrolyte.
