Patent number: 10629887Abstract: When a temperature inside a secondary battery becomes high and a gas pressure inside a battery case increases, an inversion plate is pressed due to the gas pressure so as to project and curve in a projecting manner toward an external terminal board. Due to such a deformation, a load is transmitted to a current interruption piece via a load transmission portion. At this time, due to a pushing-up force of the load transmission portion, a vulnerable breaking portion forming part of a peripheral edge of the current interruption piece breaks, so that the current interruption piece is displaced to bend in a V-shape via a folding portion. As a result, the secondary battery is brought into an unusable state. Such a configuration can attain simplification of a structure to interrupt a current.Type: GrantFiled: May 9, 2016Date of Patent: April 21, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuta Nemoto, Toshinori Okura, Takeshi Iida, Noriyuki Maruyama, Hiroaki Yoshida
