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 moduleis provided with 8 pieces of single batterieseach using a laminate film as its battery container. The 8 pieces of single batteries are disposed in a layer-stacked state. A conducting plateis placed in a manner to face one single batterydisposed at one end of the 8 pieces of the single batteries. A pushing memberis formed between the single batteryand conducting plate. A conducting plateis disposed on a side of the conducting plateopposite to the pushing member. The pushing memberhas projected portions. The conducting memberhas through-holesformed so that the projected portions are able to pass through. The conducting platesandare coupled by a coupling portion. When any one of the single batteriesand single batteryexpands at a time of abnormal battery operations, the projected portions pass through the through-holes to break off the coupling at the coupling portion
