Document Type and Number:
Japanese Patent JP7055404
Kind Code:
B2
Abstract:
In a battery module including a plurality of battery cells, a module housing storing the battery cells, and a gap-filling material loaded in the module housing, a comparatively simple structure may improve stability of the battery cells incorporated in the battery module and provide measures for heat dissipation.The battery cells are in a flat shape and stores battery elements in a flexible film pouch. The gap-filling material is made of a silicone elastic material containing a thermally conductive filler and having hardness of 80 or more in terms of E hardness or 60 or more in terms of A hardness. The gap-filling material is loaded between the battery cells and between the battery cell and the module housing on one side in a direction intersecting a direction in which the battery cells are arrayed side by side with flat surfaces of the battery cells 11 facing each other. The gap-filling material adheres to the battery cells to retain a space between the battery cells 11 and to conduct heat generated by the battery cells 11 to the module housing 12.
