  • Thermo-mechanical treated lead and lead alloys especially for current collectors and connectors in lead-acid batteries
    Publication number: 20040112486
    Abstract: Recrystallized lead and lead alloy positive current collectors and connectors such as straps and lugs for use e.g. in lead acid batteries and electrowinning anodes, having an increased percentage of special grain boundaries in at least part of the microstructure, which have been provided by a process comprising of (i) cold or hot rolling or cold or hot extrusion or (ii) steps of deforming the lead or lead alloy, and subsequently annealing the lead or lead alloy. Either a single cycle of working and annealing can be provided, or a plurality of such cycles can be provided.
    Type: Application
    Filed: November 20, 2003
    Publication date: June 17, 2004
