Document Type and Number:
Japanese Patent JP6273079
Kind Code:
B2
Abstract:
A secondary battery is disclosed. The secondary battery includes an electrode assembly (100) comprising a first electrode plate (110) and a second electrode plate (120) that are rolled while having a separator (150) interposed therebetween; and a finishing member (200) mounted on the peripheral surface and comprising a conducting portion (230) contacting said first electrode plate (110) and a non-conductive portion (220) interposed between the conducting portion (230) and the second electrode plate (120). The secondary battery forms a short path between positive and negative electrodes when the secondary battery is penetrated, and thus the secondary battery provides an improved degree of safeness against a penetration shock caused by an external shock or a penetration test.
