This abstract first appeared for US patent application 20240413497 titled 'CYLINDRICAL SECONDARY BATTERY

Original Abstract Submitted

a cylindrical secondary battery includes an electrode assembly; a cylindrical can accommodating the electrode assembly; and a terminal portion including a rivet terminal coupled to one side in the longitudinal direction of the can and electrically connected to the electrode assembly and at least one insulator between the can and the rivet terminal to insulate the can and the rivet terminal from each other. the battery also includes a rotation preventing portion on the can and/or the terminal portion. since a structure for preventing rotation of the rivet terminal is provided on the upper surface of the can or the rivet head or the main body to which the rivet terminal is fastened, the rivet terminal may not rotate due to an external force or vibration. therefore, the stability and reliability of the secondary battery can be improved.
