ABSTRACT:
The present invention provides a secondary battery module capable of securing safety at a time of abnormal battery operations by using a film-type secondary battery. A module30is provided with 8 pieces of single batteries20each using a laminate film as its battery container. The 8 pieces of single batteries are disposed in a layer-stacked state. A conducting plate17is placed in a manner to face one single battery20adisposed at one end of the 8 pieces of the single batteries20. A pushing member14is formed between the single battery20aand conducting plate17. A conducting plate18is disposed on a side of the conducting plate17opposite to the pushing member14. The pushing member14has projected portions14b. The conducting member17has through-holes17aformed so that the projected portions are able to pass through. The conducting plates17and18are coupled by a coupling portion21. When any one of the single batteries20and single battery20aexpands at a time of abnormal battery operations, the projected portions pass through the through-holes to break off the coupling at the coupling portion21.
