Abstract: A purpose of the present invention is to provide a technique for still further improving safety by increasing the resistance change ratio in a high-temperature range in a nonaqueous electrolyte energy storage device, the internal resistance of which increases with an increase in internal temperature. In a positive electrode plate for nonaqueous electrolyte energy storage device, an intermediate layer containing an electrically conducting agent and a binder is provided between a positive electrode current collector and a positive composite layer, and as the binder in the intermediate layer, one having a mass average molecular weight larger than that of a binder in the positive composite layer is used. Consequently, the resistance change ratio in a high-temperature range can be increased.

Abstract: The present invention aims at improving both of power characteristics and a capacity retention ratio of a nonaqueous electrolyte secondary battery. A nonaqueous electrolyte secondary battery according to the present invention is characterized in that a negative electrode contains an aqueous binder as a binder and amorphous carbon as a negative active material, and an average particle size of the amorphous carbon is set to a specific average particle size, which is 7 μm or less. By employing a constitution of this characteristic, both of power characteristics and a capacity retention ratio of the nonaqueous electrolyte secondary battery can be improved.

Abstract: A plurality of power storage cells and a plurality of power storage cell holders are stacked alternately in the stacking direction. End plates are superimposed at opposite ends of the power storage cells and power storage cell holders. The end plates are connected by a frame, the frame is covered by an insulator, and the plurality of power storage cells are electrically connected by a bus bar plate, forming a power storage module. Since the surface of the power storage cell is formed from a covered portion covered by the condensation-preventing sheet and a non-covered portion not covered by the condensation-preventing sheet, and the non-covered portion is covered by the power storage cell holder, the insulator, and the bus bar plate, the non-covered portion is covered as much as possible to provide heat insulation, minimizing occurrence of condensed water and preventing formation of a liquid junction.
