摘要:
A cylindrical alkaline storage battery including a spiraled electrode body composed of a pair of opposed electrodes spirally rolled up through a separator and coupled within a cylindrical casing, at least one of the electrodes being in the form of a non-sintered type electrode composed of an active material retention substrate of three dimensionally meshed structure impregnated with paste of an active material, and a current collector formed with a disc portion for connection to one end portion of the non-sintered type electrode and a lead portion for connection to a terminal, wherein the one end portion of the non-sintered type electrode is formed without impregnation of the paste of the active material, and wherein a perforated sheet metal welded to the one end portion of the non-sintered type electrode is welded at its side edge to the disc portion of the current collector.
