Abstract
A partition member has two surfaces in a thickness direction, and separates single cells that make up an assembled battery. When the average temperature of one of the two surfaces exceeds 180° C., a thermal resistance per unit area (θ1) in the thickness direction satisfies Expression 1 below, and when the average temperatures of both of the two surfaces do not exceed 80° C., a thermal resistance per unit area (θ2) in the thickness direction satisfies Expression 2 below. θ1≥5.0×10−3 (m2·K/W) (Expression 1), andθ2≤4.0×10−3 (m2·K/W) (Expression 2).
