Abstract
Provided is a battery pack having a plurality of single cells connected to one another, the battery pack being capable of preventing a temperature elevation caused by a short-circuit current that is generated when a sharp conductive foreign matter penetrates each of the single cells. In the battery pack disclosed herein, the single cells are arranged alternately adjacent to one another, and these adjacent single cells are electrically connected in series, and layered electrode bodies of these single cells have the following configurations. Among positive electrode sheets and negative electrode sheets, a negative electrode sheet is disposed on the uppermost stream side, and an endothermic agent is disposed as a layer between this negative electrode sheet and a positive electrode sheet. A negative electrode sheet is disposed on the lowermost stream side, and an endothermic agent is disposed as a layer between this negative electrode sheet and an inner surface of a battery case.
