Abstract

PURPOSE:To prevent poor electric resistance welding of electrode poles used for connection between cells in lead storage battery by forming the electrode poles with Pb-Cd-Sn alloy. CONSTITUTION:A lead storage battery is formed by electric resistance welding of electrode poles 1a, 1b used for connection between cells. The electrode poles 1a, 1b comprise Pb-Cd-Sn alloy and are allocated for covering a through hole 3 provided on a polypropylene-made bulkhead 2. Composition of the alloy is 0.005-1 wt.% of Cd, 0.1-4 wt.% of Sn and remaining of Pb. First, extruded electrodes 4a, 4b are used for pressing and deforming electrode poles 1a, 1b to be in contact with, and then welded parts 5 between cells are completed by resistance welding. By the arrangement, electrode poles 1a, 1b used for connection between cells are completely prevented from poor welding.
