Electrode plate for lead-acid battery and manufacturing method thereof |
摘要 |
A lead-acid battery electrode plate is manufactured by consecutively supplying a lead or lead alloy sheet; leaving a part in the vicinity of the center of the sheet as a non-expansion portion and expanding both sides like mesh to form a grid body; filling active material paste into the grid body; and cutting the grid body to predetermined dimensions. In the lead-acid battery electrode plate, the non-expansion portion forms a current collector part of the electrode plate along an expansion portion in an up and down direction of the electrode plate. One or more openings are made in a part of the non-expansion portion. A part of the non-expansion portion is projected above the position of an upper margin of the cut expansion portion as a current collector lug part. When the current collector lug part is placed upside, the expansion direction is the width direction of the electrode plate. <IMAGE> <IMAGE> |
