Patent number: 10084210Abstract: Provided is an electrochemical cell module in which a plurality of electrochemical cell modules may be used in a combined state. In an electrochemical cell module 1 where both ends of six cylindrical electrochemical cells (lithium ion battery cells 3) electrically connected to one another and arranged juxtaposedly are respectively held by a pair of cell holders 5 and 7, and a control circuit holder 9 is attached to an outside of the cell holder 5, which is one of the pair of the cell holders 5 and 7. The control circuit holder 9 receives a control circuit 41 operable to control voltages of the six lithium ion battery cells.Type: GrantFiled: February 28, 2013Date of Patent: September 25, 2018Assignee: Hitachi Chemical Company, Ltd.Inventors: Yuichiro Mishiro, Masahiko Amano, Masanori Niida

Patent number: 9502709Abstract: A secondary battery in which the contact resistance is not increased even if the number of housed electrodes is increased is provided. Two screw holes 11d are formed in an opposed surface 11c of a terminal body portion 11b of a positive terminal 11 that faces the stacking direction. A projecting surface 11e is provided between the two screw holes 11d to project toward a positive pressing member 25 with respect to portions provided with the screw holes 11d. The projecting surface 11e projects toward the positive pressing member 25 by 0.2 mm with respect to the portions provided with the two screw holes 11d.Type: GrantFiled: July 16, 2013Date of Patent: November 22, 2016Assignee: Hitachi Chemical Company, Ltd.Inventors: Satoshi Kugino, Yuichiro Mishiro, Mitsumasa Nakano

Patent number: 9240576Abstract: If a non-aqueous electrolyte secondary battery has a seal structure between a lid and an electrode terminal in which a seal member is compressed by fastening a nut, the nut may be loosened to make the amount of compression of the seal member insufficient to reduce the seal performance even if the nut is fastened enough to obtain an appropriate amount of compression of the seal member at the time of manufacture of the battery. A battery case has an opening, and houses an electrode group and an organic electrolyte. A lid is fastened to the battery case, and tightly seals the opening of the battery case. An electrode terminal is electrically connected to the electrode group. The lid and the electrode terminal face each other via an elastic member.Type: GrantFiled: September 21, 2011Date of Patent: January 19, 2016Assignee: Shin-Kobe Electric Machinery Co., Ltd.Inventors: Satoshi Kugino, Yuichiro Mishiro, Murashi Shinto, Kenzou Ikeda, Akira Tanaka

Patent number: 9231270Abstract: The present invention provides a cylindrical lithium-ion secondary battery. The lithium-ion battery of the present invention has a structure in which the value of B/A is optimized, where the distance between an electrode pole to which strip-form lead pieces are welded, the lead pieces being formed intermittently in the winding direction, which is the longitudinal direction of the belt-like electrodes, and the inner wall of the battery can is represented by A, and the distance between the electrode pole and the wound electrode group is represented by B, in order to secure an exhaust passage for the gas generated upon occurrence of an abnormality in the battery.Type: GrantFiled: February 15, 2012Date of Patent: January 5, 2016Assignee: Shin-Kobe Electric Machinery Co., Ltd.Inventors: Tadashi Yoshiura, Yuichiro Mishiro
