Japanese Patent JP2010113913
Kind Code:
A
Abstract:
To provide a method of manufacturing a base for a lead-acid battery, facilitating base molding work of a rolled plate and greatly improving life performance due to degradation of a positive electrode in a lead-acid battery.
The method of manufacturing the base for a lead-acid battery includes steps of: rolling out an ingot of a Pb-Ca-Sn lead alloy; subjecting the lead-alloy rolled sheet to a heat treatment for 15 minutes or longer at a temperature between 280C and a melting point of the sheet; molding the base by an expanding or stamping method within 168 hours after the heat treatment; and performing aging after the molding.
