  • Publication number: 20210083236
    Abstract: A cylindrical secondary battery may have an insulation layer formed in a region in which the top cap and the first gasket are coupled to each other. The insulation layer may include a ceramic material and a binder. The secondary battery is designed so that, when an external electrical conductive object is electrically connected directly to a positive electrode and a negative electrode of the secondary battery, an electrode tab of the secondary battery is broken as quickly as possible.
