Abstract
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.
