    摘要： A battery assembly includes a plurality of battery modules electrically connected together, each battery module acting as a secondary battery and including an electrode group, an electrolyte, a container for housing the electrode group and the electrolyte, and a safety valve operating in accordance with the internal pressure of the container. The working pressure of each safety valve is set so that the safety valve of at least one battery module is opened when the at least one battery module has its maximum internal pressure or less during the charge equalization. It is possible to provide a battery assembly that can improve the reliability of the container strength by keeping the working pressure of each safety valve lower than the pressure that the container resists even under elevated temperature conditions.

    摘要： A method for manufacturing a positive electrode for an alkaline storage battery that achieves excellent filling characteristics for an active material for the positive electrode and longer lifetime of the battery is provided. The method includes a first process of filling a paste of the active material for the positive electrode in a first porous metal sheet 30 provided with a plurality of oblate pores 30a whose major axes are arranged substantially in one direction, and a second process of pressing the first porous metal sheet 30 that has undergone the first process using a roller press such that the one direction and a direction of a rotation axis 31a of a roller 31 in the roller press substantially are parallel, so as to produce a positive electrode sheet 40 provided with a second porous metal sheet. In the second porous metal sheet, a value obtained by dividing a length of the pores in the one direction by that of the pores in a direction perpendicular to the one direction and parallel to a surface of the second porous metal sheet averages in the range of 0.9 to 1.1.

    摘要： A rectangular alkaline storage battery includes a plurality of rectangular positive electrode plates (1), negative electrode plates(2), and separators (3). The positive and negative electrode plates are layered alternately via the separators, resulting in a group of electrode plates. The group of electrode plates, together with an alkaline electrolyte, is housed in a rectangular container. In the battery, internal resistance is 5 mΩ or less, the electrode plate group thickness is 30 mm or less, and the amount of electrolyte is 1.3 to 8.0 g/Ah. This can achieve a rectangular alkaline storage battery that provides the optimum balance in the quantity of heat generation, heat release, and heat accumulation, high power, and excellent battery characteristics even when charged/discharged repeatedly and used for a long time.
