ABSTRACT:
Connecting plates of a sufficiently large thickness can be respectively connected to terminals attached to positive and negative sides, respectively, thereby providing a cylindrical cell which is suitable for supplying a large current and a cell pack using the cylindrical cell.
A cell holder is provided in which upper and lower end portions of cylindrical cells are held by a pair of supporting members provided with a vent hole, thereby allowing heat generated from the cylindrical cells to be dissipated to the exterior via the vent hole.
In order to attain the objects, in a cylindrical cell, terminals are attached to the cover on the positive side and the bottom face of the case on the negative side, respectively. Each of the terminals consists of a face portion in which a female threaded hole is opened or a male threaded portion is erected, and legs which are formed by bending the four sides of the face portion. The legs are spot-welded to the cover and the bottom face of the case. A connecting member of a sufficiently large thickness is screwed by a bolt to the terminals. A part or whole of the connecting member is configured by a flexible material.
