PROBLEM TO BE SOLVED: To provide a positive electrode mixture which can be preferably used for a positive electrode mixture layer of an all-solid type lithium sulfur battery arranged to make the most of the superior physical property that sulfur has, and having a superior charge and discharge capacities; and to provide an all-solid type lithium sulfur battery having a positive electrode mixture layer including the positive electrode mixture.SOLUTION: A positive electrode mixture comprises (A)an ion conductive substance containing phosphorus, provided that the weight ratio of the phosphorus is 0.2-0.55, (B)sulfur and/or a discharge product thereof; and (C)conductive materials. The content of the (B) component is 40 wt.% or more to the total weight of the (A), (B) and (C) components. The (C) component includes conductive materials having an average particle diameter of 0.2-200 μm, of which the specific surface area (C1) is 1800 m/g or more. The positive electrode mixture is intended for use in a positive electrode mixture layer of an all-solid type lithium sulfur battery. |
