二次電池および二次電池の制御方法
Document Type and Number:
Japanese Patent JP6753510
Kind Code:
B2
Abstract:
Provided is a secondary battery with which any temperature increase in a power generation element of the battery can be minimized even when a conductor enters the power generation element. A secondary battery (1) comprises: a power generation element (100) having a unit cell layer (14b) in which a positive electrode (12), a separator (15), and a negative electrode (13) are stacked in the stated order; an electroconductive member (32) disposed on one outward side of the power generation element (100) with an insulation member (31) interposed therebetween; a lead wire (33) connecting the electroconductive member (32) with a negative electrode tab (17a); a coil (41) that detects whether or not current is flowing to the lead wire (33); and an external discharge safety circuit (36) provided with a switch (42) that short-circuits a positive electrode tab (16a) and the negative electrode tab (17a) outside the power generation element (100) when the coil (41) has detected current.
