Publication number: 20080305393Abstract: A lithium-ion secondary battery where a current collecting member and a foil are joined to each other securely while damage of the foil is suppressed is provided. The lithium-ion secondary battery is provided with a winding group obtained by winding a positive electrode plate and a negative electrode plate via a separator. An end portion of a positive electrode mixture non-application portion and an end portion of a negative electrode mixture non-application portion project at an upper portion and a lower portion of the winding group, respectively. Current collecting disks 7 are disposed so as to face both end faces of the winding group, respectively. The current collecting disk 7 has projecting ridge portions 8 on a face thereof opposite to the winding group and flat face portions facing the winding group at positions corresponding to the projecting ridge portions 8. The projecting ridge portions 8 are formed radially.Type: ApplicationFiled: March 27, 2008Publication date: December 11, 2008Applicant: HITACHI VEHICLE ENERGY, LTD.Inventors: Kenji NAKAI, Akinori TADA, Seiichi SATO, Masatsugu ARAI

Publication number: 20050280757Abstract: In order to reduce the number of processes for manufacturing spacers and to prevent quality degradation resulting from a cell gap, a spacer 115 in a semi-transmission area 12 is formed outside of a region of a bump layer 118B. Thus, it is made possible to manufacture the spacer in the transmission region 11 and the spacer outside of the region of the bump layer in the same process. Accordingly, the number of processes can be reduced. Moreover, it is made possible to determine the cell gap in the semi-transmission area 12 by a single element of a spacer. Accordingly, precision degradation of the cell gap, which results from the bump layer, can be prevented, and high display quality can be obtained.Type: ApplicationFiled: May 31, 2005Publication date: December 22, 2005Applicant: Toshiba Matsushita Display Technology Co., Ltd.Inventors: Yoshitaka Yamada, Hirokazu Morimoto, Seiichi Sato, Hiroyuki Kimura, Tetsuya Iizuka
