PROBLEM TO BE SOLVED: To suppress occurrence of distortion in a flat surface part of a winding body within a secondary battery including a battery container formed from a film-like package when repeating a charge/discharge cycle in a secondary battery module.SOLUTION: A secondary battery module 100 comprises: a secondary battery 1 with which a flat winding body 4 is accommodated in a battery container 2 that is formed from a film-like package and in which an opening 2A of the battery container 2 is closed by a cover plate 3 to which the winding body 4 is fixed; and housings 101, 102 and 103 in which a plurality of secondary batteries 1 are fixed while being arranged side by side. The secondary battery module also comprises a partition plate 111 that is disposed between the plurality of secondary batteries 1 and separates the secondary batteries 1. The partition plate 111 is abutted to each of cover plates 3 while interposing a portion of the partition plate 111 between the cover plate 3 at one side and the cover plate 3 at the other side that are neighboring to each other.SELECTED DRAWING: Figure 6 |
