摘要： PROBLEM TO BE SOLVED: To principally solve such a problem that welding is difficult when configuring a sealing body, because a plane for welding a positive electrode cap and the sealing body is very narrow, in a battery module in which cylindrical secondary batteries are fixed by welding via a projection formed in a sealing plate.SOLUTION: The cylindrical secondary battery includes a battery outer can having an opening also serving as the terminal of one pole, a sealing body also serving as the terminal of the other pole located at the opening, and an electrode body in which a collector is connected with the end of at least one of positive and negative electrodes housed in the battery outer can. A positive electrode cap constituting the sealing body has a space for housing a valve body and a flange. The flange is formed at an acute angle with the sidewall of the space, and the flange and sealing body are fixed by welding.

摘要： PROBLEM TO BE SOLVED: To provide a cylindrical secondary battery with excellent output characteristics by reducing internal resistance through the use of a current-collecting lead with excellent current-collecting properties.SOLUTION: A cylindrical secondary battery of the present invention is configured such that a current-collecting lead 10 is welded to a collector welded to an upper portion of an electrode group and the current-collecting lead 10 is also welded to a sealing assembly sealing an opening of an outer can. The current-collecting lead 10 formed to have a substantially same diameter as an outer diameter of the collector comprises: a flat surface part 11 welded to the collector; and a top part 12 which is curved and protrudingly formed in a substantially dome shape from the flat surface part 11, and which is welded to the sealing assembly. A central opening 12a is formed at a central portion of the top part. Around the central opening 12a, a plurality of welding projections 12c are formed to protrude toward the sealing assembly. The welding projections serve as welding spots to the sealing assembly. The top part 12 is deformed by pressing force from the sealing assembly to be brought into surface contact with a corner portion of a convex portion formed on a lower surface of the sealing assembly.
