Battery with tabs having superimposed bundling members
First Claim
1. A battery, comprising:
- a cathode; and
an anode;
at least one of said cathode and anode including;
an electricity collector having a side and a surface;
a plurality of tabs having an end projecting from the side of the electricity collector, and being bonded integrally with the electricity collector; and
an active material formed on the surface of the electricity collector,wherein the electricity collector is laminated so as to make an end surface flush on the side of the electricity collector from which the tabs project, andeach tab comprises;
a linkage member projecting from the side of the electricity collector, anda bundling member formed integrally with the linkage member, extending substantially parallel to the side of the electricity collector from which the tabs project, said bundling member being superimposed on other bundling members, and being bonded with other bundling members.

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.
