Title:
METHOD FOR MANUFACTURING ELECTRODE PLATE GROUP FOR LEAD-ACID BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/109315
Kind Code:
A1
Abstract:
Provide is a method for manufacturing an electrode plate group for a lead-acid battery capable of shortening the time required for melting pig lead to produce molten metal when forming a strap. The method for manufacturing an electrode plate group for a lead-acid battery is constituted by first to third processes. In the first process, unheated pig lead made of lead or a lead alloy is preliminarily heated up at a heating station (6) to a temperature at which the lead does not melt. In the second process, the preliminarily heated pig lead (7) is heated at a melting section (8) to a temperature at which the lead is melted to make a molten metal (9). The molten metal (9) is injected into a mold (10), and the cathode ear parts (4) or anode ear parts (5) of electrode plates of the same polarity are immersed in the molten metal (9) in the mold (10) to form a strap. The first process is then executed during the execution of the second process.
