|20140220406||CONDUCTIVE CONNECTION STRUCTURE FOR SECONDARY BATTERIES - A conductive connection structure for secondary batteries employs conductive portions disposed under two lateral sides of a cover plate to conductively connect to at least one battery cell. The conductive portions disposed under the two lateral sides of the cover plate are bendable, and the conductive portions are bent toward outer sides of the cover plate, so that the conductive portions are disposed horizontally; a connecting portion is extended upward respectively from an anode and a cathode terminals on two lateral sides of each of the battery cells, and the connecting portions and the conductive portions are electrically connected. By modifying the design of the connection structure of the battery cells and the two conductive portions under the cover plate, a time for soldering the battery cells and the conductive portions for conductive connection is reduced, the connection is tighter and more reliable and manpower cost is reduced.||08-07-2014|
