Title: Safety structure of lithium secondary battery
Inventor: MURAKAMI FUMIAKI
IPC: H01M10/0587
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a safety structure of lithium secondary battery capable of interrupting a current path with a simple structure, a small number of part items and a saved space. SOLUTION: In a battery, a current path from a current collecting plate 2 to a positive or negative electrode terminal through a positive electrode 1 or a negative electrode core bar 11 is constituted by winding a roll electrode 3 on a core 12 consisting of an insulating core bar 5 and the positive electrode 1 and negative electrode core bar 11 mechanically connected to the upper and lower parts thereof, housing it in a facing can 20, electrically connecting the current collecting plate 2 to the end surface of the roll electrode, fixing one end of a positive or negative electrode terminal 4 to a lid 9 for sealing the opening part of the facing can 20, and fixing the other end to the positive electrode or negative electrode core bar 11 connected to the current collecting plate 2. A low strength part 1a is provided on the positive electrode 1 or negative electrode core bar 11.  Since the lid 9 for sealing the facing can 20 is swollen and displaced out of the battery when the battery internal pressure is raised in a battery abnormality such as overcharge or over discharge, a tensile stress acts on the positive electrode core bar or negative electrode core bar 1, and the low strength part 1a is ruptured to interrupt the current path, so that the further internal pressure rise can be stopped.
