摘要： An alkaline storage battery has an electrode terminal that is inserted in a penetration hole, and disposed astride an inside of a battery case and an outside of the battery case, and fastened to a hole periphery portion via a packing. The negative terminal has a seal portion that, together with the hole periphery portion, clamps and compresses the packing to liquid-tightly seal the penetration hole. The seal portion includes an annular seal surface located facing the hole periphery portion, and a seal periphery surface located around the seal surface. The seal surface is protruded from the seal periphery surface toward the hole periphery portion. The surface roughness Ry of the seal surface of the negative terminal is 15 μm or less.

摘要： A sealed prismatic battery has a battery case made of a plurality of prismatic cell cases coupled together via partition walls. Electrode plate groups are accommodated together with liquid electrolyte in each of the cell cases. Each electrode plate group consists of alternately stacked-up positive and negative electrode plates with separators interposed therebetween, lead portions of positive and negative electrode plates being protruded on opposite sides. Collectors are bonded to these lead portions. Between the collectors and end walls (and/or partition walls) of the battery case are provided conductive plates that are connected to the collectors one or more than one location in their middle part so as to decrease the resistance between connection terminals and the electrode plate groups.

摘要： A cell includes an electrode plate group which is formed by laminating a positive electrode plate and a negative electrode plate with a separator interposed between them, and includes leads protruding toward directions opposite to each other from one side of the positive electrode plate and the negative electrode plate, collectors which are joined to the leads on both sides of the electrode plate group, and include connection protrusions formed so as to protrude outside, and a bag-shape battery case containing the electrode plate group joined to the collectors such that only the connection protrusions of the collectors are protruded outside. A battery module is constituted by placing a plurality of the cells in a prismatic battery case while the connection protrusions of the collectors of the cells are connected with each other, thereby making the current-carrying path between the electrode plate groups straight and short and increasing the output.

摘要： In a battery pack including a plurality of prismatic rechargeable batteries arranged in parallel with ventilation spaces being provided therebetween, the battery pack is constituted so that cooling air is downwardly sent from above the battery pack through the ventilation spaces. In accordance with a temperature detected with a temperature detection sensor attached to the lower end of the rechargeable battery, a blower fan is controlled by a control section. Moreover, a sensor placement concave, which is separated from a space inside a battery case through a thin partition wall, is provided on a bottom wall of the battery case of the rechargeable battery. The temperature detection sensor is placed in the sensor placement concave so as to be pressed against the partition wall.
