Abstract: The invention relates to a storage battery module (10) that includes a housing (12), a plurality of storage battery cells (14) in the housing (12), and a cover layer (20) in the housing (12) and above the storage battery cells (14). Each storage battery cell (14) has at least one weak point (56), and the cover layer (20) includes at least one filter mat section (22) that is gas-permeable over the entire surface and flame-arresting over the entire surface. The filter mat section (22) is situated over the entire surface above all weak points (56) of the storage battery cells (14) contained in the storage battery module (10), or a filter mat section (22) is situated above each weak point (56) of the storage battery cells (14) contained in the storage battery module (10).
