成果简介	NOVELTY - Battery (100), comprises a housing (102) having a first end (102a) and a second end (102b) opposite to the first end, a jelly roll (103) disposed within the housing; the first end having a through hole (104); a riveted terminal (106) disposed at the through hole, the riveted terminal, comprises a first portion (108) disposed at an upper section of the first end, and a second portion (110) disposed at a lower section of the first end, where the first portion comprises a central cavity, and two flanges and extending from a side wall of the first portion; the second portion comprises a sealing flange (116) connected to the lower section of the first end, and a lower cavity with an increased diameter relative to the central cavity, where circumferential wall of the lower cavity being inclined at an angle ranging from 80- 88°. USE - Battery. ADVANTAGE - The structural and functional design of a riveted terminal assembly used in batteries to enhance interlocking, electrical connectivity, and assembly efficiency. Enhanced interlocking between the riveted terminal and the current collector disc for improved mechanical stability. Increased landing area on the top surface of the current collector disc, reducing electrical resistance and enhancing welding reliability. The additional space facilitates the integration of multiple welding lines or terminals between the cathode and the riveted terminal, improving electrical performance. The use of copper materials enables ultrasonic welding, further increasing the weld area for better connectivity. The battery provides a robust solution to these challenges by ensuring the concentricity of the jelly roll during the welding process and preventing the displacement of the current collector disc/plate. This approach minimizes welding defects, enhances the structural stability of the battery, and significantly improves manufacturing efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for A method for assembling a battery. DESCRIPTION OF DRAWING(S) - The drawing shows a assembled cutaway view of the top portion of the battery. 100Battery 102Housing 102aFirst end 102bSecond end 103Jelly roll 104Through hole 106Riveted terminal 108First portion 110Second portion
