<p><P>PROBLEM TO BE SOLVED: To provide a partitioning plate for heat dissipation of a battery case which has superior oxidation resistance and alkaline corrosion resistance in addition to heat dissipation characteristic. <P>SOLUTION: In the battery case in which a plurality of unit batteries are laminated and stored, the partitioning plate 1 for heat dissipation in which neighboring unit batteries are sectioned is composed of aluminum base material having a surface treatment film, has a thickness ofδ(mm) along the lamination direction of the unit battery and a length of L (mm) along the direction perpendicular to the lamination direction, and equipped with one or more ventilation holes D penetrating along the longitudinal direction. If the maximum width of the ventilation hole in the lamination direction is F (mm) and the cross-sectional area of the ventilation hole in the lamination direction is S (mm<SP>2</SP>), then F/δ≤0.6 and 3≤L/S≤45 are satisfied in the partitioning plate for heat dissipation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
