A separating member for separating a plurality of battery cells, the separating member comprising:
- a plurality of first walls;
- and
- a plurality of second walls having a thickness larger than a thickness of the first walls,
- wherein the plurality of first and second walls each include a laminated structure,
- wherein the separating member is expandable from a collapsed state to an expanded state, the separating member having a plate configuration with the first walls being disposed parallel to the second walls in the collapsed state and having a honeycomb structure including a plurality of unit cells with the first walls being disposed at angles to the second walls in the expanded state, and
- wherein the plurality of first walls and the plurality of second walls jointly define the plurality of cell units of the honeycomb structure with an end of each of the first walls coupled to an end of one of the second walls.
