Abstract
To provide an electrode mixture which can suppress the increase in reaction resistance of an active material and a solid electrolyte even if a charge voltage of a solid battery is increased.SOLUTION: An electrode mixture of the present invention comprises: an active material containing a lithium (Li) element, a manganese (Mn) element and an oxygen (O) element; a sulfur compound containing a lithium (Li) element, a phosphorus (P) element and sulfur (S) element; and an oxide containing a lithium (Li) element, a halogen (X) (where X is at least one kind of fluorine (F), chlorine (Cl), bromine (Br) and iodine (I)) element and an oxygen (O) element. The oxide contains a crystal phase having an antiperovskite type crystal structure; the content of the oxide is 70 mass% or less to a total mass of a sulphur compound and oxide. The sulphur compound is 4 or more in the molar ratio of the sulfur (S) element to the phosphorus (P) element.SELECTED DRAWING: None
