摘要： A rectangular and sealed battery incorporating an outer can for accommodating a power generation element and a cover for closing an opening of the outer can such that the outer can and the cover are welded to each other. The thickness of a body portion of the outer can is smaller than the thickness of the opening. A flange formed into a stepped portion is provided for the outer end of the cover, and the end of the opening of the outer can is made contact with the outer surface of a projection of the cover formed by the stepped portion so as to be joined to the outer surface of the projection and butt-welded to the flange. In the foregoing case, the cover and the end of the opening of the outer can are welded to each other from a side direction.

摘要： A non-aqueous electrolyte secondary cell having a negative electrode, a positive electrode and a non-aqueous electrolytic solution, in which a carbonaceous material is used as an active negative-electrode material, is disclosed. The negative electrode is constituted by a carbon sintered mass obtained on sintering the carbonaceous material or a carbon sintered mass-current collector composite material. The secondary cell is improved in the amount of the active material packed in the negative electrode, energy density and in the charging/discharging efficiency. If the carbon sintered mass-current collector composite material is employed for the negative electrode, further improvement in the electrical conductivity and charging/discharging efficiency in the negative electrode is achieved.

摘要： A battery pack which can increase of the volumetric efficiency of the battery pack without being contained in a resin mold case is provided. A first laminate material has a concave portion formed by drawing where a battery element is contained. A second laminate material is stacked so as to cover the opening of the concave portion to seal up the periphery of the opening. The first and second laminate materials are bend inwards so as to cover the battery element, and bonded and fixed together by heating. The first laminate material has three-layer structure including a polypropylene layer, a soft aluminum layer, and a nylon layer or PET layer. The second laminate material has a similar structure but includes a hard aluminum layer. Therefore, the second laminate material has enough strength to resist deformation without being contained a cell in a resin mold case.

摘要： An extremely safe non-aqueous electrolyte secondary cell free of explosions and which can promptly release the internal pressure in case of rise in the internal pressure. The non-aqueous electrolyte secondary cell has in its opening a cleavage valve obtained on bonding a metal foil to the opening. In case of rise in the internal pressure, the cleavage valve is cleft to release the pressure. In this cell, a value K corresponding to the internal volume in the cell in cm3 divided by the area of the opening in cm2 is set so that 40≦K≦350. By selecting the value K to a suitable value, the cleavage valve is in operation when the internal pressure reaches a predetermined value to release the pressure. The metal foil is produced by, for example, a electro-forming method or a cladding method. Preferably, a fluorine-based water-proofing agent is coated on the foil surface.

摘要： There is disclosed a non-aqueous electrolyte secondary battery in which carbonaceous material is used as the anode active material and charge/discharge is carried out by doping/undoping of lithium. The carbonaceous material has a grading distribution such that the 10% cumulative or accumulated diameter is 6 to 20 .mu.m, the 50% cumulative diameter is 20 to 55 .mu.m, and the 90% cumulative diameter is 55 to 90 .mu.m. When a carbonaceous material such that the grading distribution satisfies the above condition is used as the anode active material, the self-discharge rate is suppressed and occurrence of an internal short-circuit is also prevented.
