First claim
Opening claim text (preview).
What is claimed is: 1 . An electrode layer for an all-solid state battery, the electrode layer comprising: an electrode active material; a sulfide solid electrolyte; and a residual liquid, wherein the residual liquid has a δ P of less than 2.9 MPa ½ in a Hansen solubility parameter and a boiling point of 190° C. or higher. 2 . The electrode layer according to claim 1 , wherein an amount of the residual liquid in the electrode layer is 1,500 ppm or more and 5,000 ppm or less. 3 . The electrode layer according to claim 1 , wherein the residual liquid contains at least one of a naphthalene-based compound, a lauryl group-containing compound, and a monocyclic aromatic compound. 4 . The electrode layer according to claim 3 , wherein the residual liquid contains the naphthalene-based compound. 5 . The electrode layer according to claim 4 , wherein the naphthalene-based compound is tetralin. 6 . The electrode layer according to claim 3 , wherein the residual liquid contains the lauryl group-containing compound. 7 . The electrode layer according to claim 3 , wherein the residual liquid contains the monocyclic aromatic compound. 8 . The electrode layer according to claim 1 , wherein the electrode layer is a positive electrode layer. 9 . The electrode layer according to claim 1 , wherein the electrode layer is a negative electrode layer. 10 . An all-solid state battery comprising: a positive electrode layer; a negative electrode layer; and a solid electrolyte layer arranged between the positive electrode layer and the negative electrode layer, wherein at least one of the positive electrode layer and the negative electrode layer is the electrode layer according to claim 1 .
