Patent number: 7700231Abstract: A battery, suitable for forming a battery pack, includes an electrode assembly having a positive electrode plate and a negative electrode plate, and a separator wound or laminated together, core materials of the negative and positive electrode plates being bared respectively at either end. A bottomed cylindrical outer case having a bottom is connected to either end face of the electrode assembly to serve as a battery terminal. Electrolyte is impregnated in the electrode assembly and a lid connected to the other end face of the electrode assembly and fixedly attached to the outer case with a sealer and an insulator interposed therebetween. A connecting part is a part of the lid so that the connecting part engages with and connects to a bottom part of the outer case of another battery.Type: GrantFiled: December 26, 2002Date of Patent: April 20, 2010Assignee: Panasonic CorporationInventors: Kenji Kimura, Tatsuya Hashimoto, Takabumi Fujii, Seiichi Uemoto, Hironori Yukisada, Masatomo Nagatani

Patent number: 7643608Abstract: In a method for checking for leakage from tubular batteries, when tubular batteries are fed with their respective axial centers aligned in parallel to each other to pass through a leakage check mechanism, a sealed end face of the tubular batteries is irradiated with an X-ray. In accordance with the result of analysis on whether the incident fluorescent X-ray entering a detector contains a fluorescent X-ray associated with an electrolyte component, it is determined whether the tubular batteries have leaked. A length of a detection window of the detector in a direction of feed of the tubular batteries is set to be less than a spacing between the tubular batteries. A length of the detection window oriented orthogonal to the direction of feed is set to be greater than an outer size of the cross-sectional shape of the tubular batteries oriented orthogonal to their axial center.Type: GrantFiled: November 24, 2005Date of Patent: January 5, 2010Assignee: Panasonic CorporationInventors: Hironori Yukisada, Takahito Takahashi, Masao Nakamura, Kazutoshi Okubo, Masaya Nakata

Publication number: 20080137807Abstract: In a method for checking for leakage from tubular batteries, when tubular batteries (Ba) are fed with their respective axial centers aligned in parallel to each other to pass through a leakage check mechanism (12), a sealed end face (33) of the tubular batteries (Ba) is irradiated with an X-ray (34). A fluorescent X-ray (40) coming out of the sealed end face (33) is incident upon a detector (39) through a detection window (35). In accordance with the result of analysis on whether the incident fluorescent X-ray (40) contains a fluorescent X-ray (40) associated with an electrolyte component, it is determined whether leakage has occurred from the tubular batteries (Ba). A length (L1, L3, L5) of the detection window (35) in a direction of feed of the tubular batteries (Ba) is set to be less than a spacing (C1, C2) between the tubular batteries (Ba).Type: ApplicationFiled: November 24, 2005Publication date: June 12, 2008Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Hironori Yukisada, Takahito Takahashi, Masao Nakamura, Kazutoshi Okubo, Masaya Nakata
