Patent number: 8076023Abstract: A non-aqueous electrolyte secondary battery including an electrode assembly, a non-aqueous electrolyte, and a substantially rectangular battery case for housing the electrode assembly and the non-aqueous electrolyte. The thickness ?, the width ?, and the height ? of the battery case satisfy the relation ?<???c. The electrode assembly includes a positive electrode, a negative electrode, and a porous heat-resistant layer disposed between these electrodes. The positive electrode includes a positive electrode active material layer, and the negative electrode includes a negative electrode active material layer. The ratio of the pore volume included in a predetermined area of the porous heat-resistant layer to the battery theoretical capacity is 0.18 to 1.117 ml/Ah. The predetermined area has the same area as the positive electrode active material layer. The porosity of the porous heat-resistant layer is 35 to 85%.Type: GrantFiled: April 19, 2011Date of Patent: December 13, 2011Assignee: Panasonic CorporationInventors: Hiroaki Ichinose, Masatoshi Nagayama

Patent number: 6743546Abstract: Battery with a flexible laminate casing includes a means for fixing the electrode assembly (2) within the casing (1, 18). The fixing means may be a frame (19, 33, 38, 50, 54) attached to the periphery of the electrode assembly, or an insulating spacer (59, 69, 70, 77, 78) encased within the casing together with the electrode assembly such as to fill a space between one end of the electrode assembly and the casing. Alternatively, the fixing means may be constructed of a material with which the casing and the electrode assembly are joined together by applying heat and pressure, or may be an abutting surface (87h) provided to the casing (87) itself such as to make contact with one end face of the electrode assembly within the casing.Type: GrantFiled: September 26, 2001Date of Patent: June 1, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaaki Kaneda, Hideaki Yoshio, Yoshitaka Matsumasa, Hiroaki Ichinose, Hitoshi Suzuki, Shingo Tsuda
