Abstract

PURPOSE:To easily obtain a high tightening pressure of an electrode group and improve the assembling feature by using a profile memory alloy memorizing a profile expanding the outside width of eletrodes in the lamination direction as a spacer when the electrode group is stored in a battery jar. CONSTITUTION:When an electrode group 1 composed of a positive electrode, a negative electrode, and a separator is stored in a battery jar 2 of a lead storage battery, a spacer 3 made by lapping a profile memory alloy 4 memorizing a profile expanding the outside width of electrodes in the lamination direction with synthetic resin 5 is used. Therefore, a flat-shape spacer 3 being stored at a low temperature of 0 deg.C or lower is laminated with an electrode 1 and inserted into the battery jar 3, and the spacer 3 is put in a stable condition with a wave shape expanding the outside width at a normal temperature, thereby a high tightening pressure can be applied to electrodes while the battery is used, thus the assembly is made easy and the active material is effectively prevented from peeling off.

In order to prevent its deterioration, the pressure on the polar group must be increased to 20
It is necessary to set the pressure to about 1 in ~40, but there is a problem in that if a sufficient tension force is applied at the time of assembling the pole group, the assembling work becomes extremely complicated.

That is, in the drawings, 1 is an electrode group consisting of an anode plate, a cathode plate, and a separator, 2 is a battery case, and 3 is a spacer. The spacer 6 has a structure in which a shape memory alloy 4 is covered with a synthetic resin coating 5. The shape memory alloy 4 exhibits a stable plate-like shape at a low temperature below O'C, and stably exhibits a wavy shape, which is a shape in which the external width in the stacking direction of the electrode plates increases at room temperature. The shape is memorized as shown in the state. The synthetic resin coating 5 covers the shape memory alloy 4 by placing the shape memory alloy 4 in an injection mold and injection molding the synthetic resin 9.

That is, a flat plate-shaped spacer 6 which has been stored in water or the like is laminated with the pole group 1 and immediately inserted into the battery case 2. At this time, since the spacer 6 has a flat plate shape, it can be easily inserted into the battery case 2.
