    摘要： In a battery pack including rechargeable batteries arranged in parallel, a cooling medium path for allowing a cooling medium to horizontally flow be formed between the rechargeable batteries. A cooling medium delivery device for delivering the cooling medium to the cooling medium path is provided so as to reduce a height of the battery pack including a cooling device. The cooling medium delivery device is constituted by a pair of cooling medium introduction ducts provided on both right and left sides of the battery pack, each having delivery ports for delivering the cooling medium alternately in horizontally opposed directions to each of the cooling medium paths, and a cooling medium compression transport device for supplying the cooling medium to both of the cooling medium introduction ducts.

    摘要： A sealed battery includes a metal case which functions as a connection terminal of one polarity and an electrode post which is mounted to the case in an insulated manner and functions as a connection terminal of the other polarity. A sealing section with electrical insulation properties is disposed between the electrode post formed from a hollow cylinder with one closed end and an electrode post through-hole provided in the case. A compression deformation section is produced by deforming the closed end of the electrode post radially outward, for compressing and sealing the sealing section, and for securing the electrode post to the case.

    摘要： A sealed-type secondary battery is disclosed. A battery module of a sealed-type secondary battery is formed by heating and fusing a top lid member and an integrated battery container. The integrated battery container is formed with a polymer alloy including a polyphenylene ether resin and a polyolefin resin, and the top lid member or a lateral lid member is formed with a polypropylene-based resin. A nucleating agent is added to the polypropylene-based resin of the top lid member or the lateral lid member, to improve mechanical strength, and the molecular weight is increased to reduce a melt flow rate MFR to approximately the same degree as the polymer alloy.
