PROBLEM TO BE SOLVED: To provide an electrode filled with an active material in an opening section and stuck with no active material on a lug by filling the active material in a continuous lattice made of a lead alloy, then partially removing the filled active material, and partially exposing a lattice surface. SOLUTION: For manufacturing an expand electrode, a rolled sheet made of a lead-calcium-tin alloy is manufactured. Both ends of the rolled sheet are deployed by a reciprocating expanding machine, and an opening section is punched. An active material paste is filled on the whole surface of this lattice. At the time of filling, pasting papers are put on the surface and back face of the electrode and are stuck to the electrode by roll press. The filled electrode is cut in a prescribed size, and the cut electrode is sent to a drying furnace. The active material is stuck to the electrode lug 10 of the electrode, and the active material on the electrode lug 10 is removed with a rotary brush. The active material on the surface of the electrode lug 10 is completely removed, and a metallic gloss is shown. Aging is then applied to the electrode. |
