Abstract
A method for producing a prismatic secondary cell housing a flat electrode assembly includes disposing a first current-collecting member onto a first to-be-welded portion at a flat portion of an edge of the electrode assembly where a core-body exposed portion of the first electrode protrudes. A first receiving member is disposed onto a plane opposing the flat portion. The first current-collecting member, the core-body exposed portion, and the first receiving member are resistive-welded with the core-body exposed portion between the other members. A second current-collecting member is disposed onto a second to-be-welded portion at a position of the flat portion distanced from the first to-be-welded portion while avoiding contact between the collecting members. A conductive connecting member is placed between the collecting members or between the receiving members. The conductive connecting member and its abutting members are welded. One of the members is electrificably connected to an external output terminal.
