摘要： An assembled battery is provided which can improve output density. Four unit cells are connected in series by a connection member 40 composed of a stacked metal plate obtained by stacking two metal plates 40a and 40b. The metal plate 40a is one of copper and aluminum while the metal plate 40b is nickel. Since the volume electrical resistance of both copper and aluminum is less than half that of nickel, the overall electrical resistance of the connection member 40 is lowered. Both end portions of the connection member 40 are joined to external electrode terminals by resistance welding so that the weld joint is formed from either a Cu—Ni or Al—Ni low resistance binary alloy.

摘要： 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 module 30 is provided with 8 pieces of single batteries 20 each using a laminate film as its battery container. The 8 pieces of single batteries are disposed in a layer-stacked state. A conducting plate 17 is placed in a manner to face one single battery 20a disposed at one end of the 8 pieces of the single batteries 20. A pushing member 14 is formed between the single battery 20a and conducting plate 17. A conducting plate 18 is disposed on a side of the conducting plate 17 opposite to the pushing member 14. The pushing member 14 has projected portions 14b. The conducting member 17 has through-holes 17a formed so that the projected portions are able to pass through. The conducting plates 17 and 18 are coupled by a coupling portion 21. When any one of the single batteries 20 and single battery 20a expands at a time of abnormal battery operations, the projected portions pass through the through-holes to break off the coupling at the coupling portion 21.
