    • A cylinder-shaped secondary battery includes a container, and a rolled electrode. The container includes a cylinder-shaped inner member, a cylinder-shaped outer member, and a pair of ring-shaped end plates. The electrode is accommodated in the container in an electrically insulating manner, rolled spirally, and has a pair of tabs and a hollow formed therein and extending in an axial direction thereof. Moreover, the electrode includes a positive electrode, a negative electrode and a separator disposed between the positive electrode and negative electrode so as to separate them. The inner member of the container has opposite ends and a hollow formed therein and extending in an axial direction thereof, and is disposed in the axially-extending hollow of the electrode. The outer member of the container has opposite ends, and is disposed on a centrifugal side of the electrode. The end plates of the container close the opposite ends of the inner and outer members, and are pierced through by terminals of the battery in an electrically insulating manner. Moreover, the end plates are bonded to the opposite ends of the inner member and/or the outer member by welding. The thus constructed battery has such good heat-radiating ability and high pressure resistance that it can stably carry out its functions.
    • 圆筒形二次电池包括容器和卷绕电极。 容器包括圆柱形内部构件,圆柱形外部构件和一对环形端板。 电极以电绝缘方式容纳在容器中,螺旋地卷起,并且具有形成在其中并沿其轴向方向延伸的一对凸片和中空部。 此外,电极包括正极,负极和设置在正极和负极之间的隔板,以分离它们。 容器的内部构件具有相对的端部和形成在其中并且沿其轴向方向延伸的中空部,并且设置在电极的轴向延伸的中空部中。 容器的外部构件具有相对的端部,并且设置在电极的离心侧。 容器的端板封闭内部和外部构件的相对端,并以电绝缘的方式穿过电池的端子。 此外,端板通过焊接与内部构件和/或外部构件的相对端部接合。 这样构成的电池具有能够稳定地实现其功能的良好的散热能力和耐高压性。

    • A battery includes a cathode, and an anode. At least one of the cathode and anode includes an electricity collector, a plurality of tabs, and an active material formed on the surface of the electricity collector. One end of the tabs projects from one side of the electricity collector. The electricity collector is laminated so as to make a flush end surface on the side from which the tabs project. The tabs are bonded integrally with the electricity collector, and each tab has a linkage member, and a bundling member. The linkage member projects from the side of the electricity collector. The bundling member is formed integrally with the linkage member, extends along the side of the electricity collector, is superimposed on other bundling member of the tab in a lamination direction of the laminated electricity collector, and is bonded integrally with other bundling member of the tab. In the thus constructed battery, the projection of the tabs are kept down to the width of the tab. As a result, it is possible to minimize the space required for integrally bonding the tabs, and to thereby enhance the energy density of the battery.
    • 电池包括阴极和阳极。 阴极和阳极中的至少一个包括集电器,多个突片和形成在集电器表面上的活性材料。 标签的一端从集电器的一侧突出。 集电器被层压,以便在突出部分突出的一侧形成平齐的端面。 突片与集电器一体地结合,每个突片具有连接构件和捆扎构件。 连接构件从集电器的侧面突出。 捆扎构件与连接构件一体形成,沿着集电器一侧延伸,在叠层集电体的层叠方向上叠置在突片的其他捆扎构件上,并与片的另一个捆扎构件 。 在如此构造的电池中,突片的突起保持下降到突片的宽度。 结果,可以将突片一体地接合所需的空间最小化,从而提高电池的能量密度。
