Summary:In the present invention, a partition member that partitions unitary batteries in a battery assembly is configured so as to readily suppress the incidence of water condensation in the interior of the battery assembly. The partition member 1 is configured by enclosing an internal capsule member 110 inside an outer package member 120. The internal capsule member 110 is formed including a porous body, and the water-vapor permeability of the outer package member 120 in a 40°, 90% RH environment is set to 1.0×10-3 to 5.0×101g/m2/day. Dans la présente invention, un élément de séparation qui sépare des batteries unitaires dans un ensemble de batteries est conçu de façon à supprimer facilement l'incidence de condensation d'eau à l'intérieur de l'ensemble de batteries. L'élément de séparation 1 est conçu en enfermant un élément capsule interne 110 à l'intérieur d'un élément boîtier externe 120. L'élément capsule interne 110 est formé et comprend un corps poreux et la perméabilité à la vapeur d'eau de l'élément boîtier externe 120 dans un environnement à 40°, 90 % de HR est établie entre 1,0×10-3 et 5,0×101 g/m2/jour. 組電池の単電池間を仕切る仕切り部材において、組電池内部での凝縮水の発生を抑制しやすくするように構成する。 外装材120内に内包材110を収容して仕切り部材1を構成する。前記内包材110は多孔質体を含んで形成し、前記外装材120はその40℃、90%RH環境下における透湿度を1.0×10-3~5.0×101g/m2/dayに設定する。
