PROBLEM TO BE SOLVED: To provide, as embodiments, an assembled battery and a battery pack which are arranged so as to be able to prevent a short circuit caused by liquid between unit battery cells connected in series in a battery cell.SOLUTION: An assembled battery according to an embodiment comprises: a plurality of nonaqueous electrolyte batteries. Each nonaqueous electrolyte battery comprises: current correctors; a positive electrode having a positive electrode active material layer on each face of the current collector; a negative electrode having a negative electrode active material layer on each face of the current collector; and a nonaqueous electrolyte. The nonaqueous electrolyte battery has a laminate including the positive and negative electrodes. The assembled battery is arranged by providing sheet-like leads larger, in area, than the nonaqueous electrolyte batteries between the nonaqueous electrolyte batteries into a group; and folding the group of the nonaqueous electrolyte batteries and the leads so that they alternate.SELECTED DRAWING: Figure 3

    【課題】 実施形態は、セル内部で直列接続した際の単位セル同士の液洛を防ぐことができる組電池及び電池パックを提供することが課題である。【解決手段】 実施形態の組電池は、集電体と、正極電極と、負極電極と、非水電解質とを具備する。正極電極は、前記集電体の両面に正極活物質層を有する。負極電極は、前記集電体の両面に負極活物質層を有する。前記正極電極と前記負極電極とを有する積層体からなる非水電解質電池を複数設ける。前記非水電解質電池の面積よりも面積が大きいシート状のリードを前記非水電解質電池間に配設し、前記非水電解質電池と前記リードとを交互に折り重ねて積層させたものである。【選択図】図3
