摘要： PURPOSE:To obtain a battery preventing the infiltration of moisture into a battery can body and preventing a liquid leak during storage under high- temperature, high-humidity conditions. CONSTITUTION:A battery has a seal member 6 made of nylon for sealing the opening of a battery can body 1, a current collecting pin 5, a reinforcing member 7 reinforcing the seal member 6, a plate-shaped spring 8 for pressing the current collecting pin 5, and a cover 9. A thin section 6a to be broken when the battery internal pressure becomes high is formed on the seal member 6, and gas vent holes 7a, 8a, 9a are formed on the reinforcing member 7, plate- shaped spring 8 and cover 9 respectively. The gas vent hole 7a of the reinforcing member 7 is closed by a waterproof member 15 coated with resin, thus no moisture infiltrates into the battery can body 1. When the battery internal pressure rises and the thin section 6a is broken, the internal pressure is applied to the waterproof member 15, the waterproof member 15 is removed from the gas vent hole 7a, and the battery internal pressure is released. The battery may be constituted so that the gas vent hole 8a or 9a is closed.

摘要： PURPOSE:To enhance a heavy-load discharging characteristic by setting a compounding ratio of a conductive material added in an electrode agent layer disposed outside of a collector larger by an adequate ratio than that of another conductive material added in an electrode agent layer disposed inside the collector. CONSTITUTION:When a compounding ratio of a conductive material added in an electrode agent layer disposed outside a collector around which a laminated electrode is spirally wound is Xawt% and a compounding ratio of a conductive material added in an electrode agent layer disposed inside the collector is Xbwt%, Xa/Xb ranges from 1.17 to 1.83, thereby increasing a discharging capacity at the time of a heavy load without decreasing a discharging capacity at the time of a light load. As the conductive material added in the electrode agent, stable and inexpensive graphite powder having low specific gravity is used.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of active material and the abnormal precipitation of the active material on a battery surface, to thereby prevent the lower capacity of a nonaqueous electrolyte secondary battery due to repetition of its charging/discharging. SOLUTION: Outer periphery layers 13, 23 of at least one electrode of a negative electrode 1 and a positive electrode 2 are made thicker than inner periphery layers 12, 22 of the electrode, so that charging/discharging reactions between each of the outer periphery layers 13, 23 of the negative electrode 1 or the positive electrode 2 and each of the inner periphery layers 12, 22 of the positive electrode 2 or the negative electrode 1 is almost uniform between these electrode active materials, whereby the amount of the active material on the outer periphery layer 13, 23 also becomes greater than the amount of active material on the inner periphery layers 12, 22. Load on the outer periphery layers 13, 23 of the active material during charging/discharging is reduced nearly to that of the inner periphery layers 12, 22.
