摘要： Disclosed is a secondary battery having a constant-voltage device for preventing the secondary battery from being excessively overcharged. The breakdown voltage of the constant-voltage device is lower than the explosion or ignition voltage of the secondary battery, so the discharge operation may occur before the secondary battery is exploded or ignited even if the voltage of the secondary battery rises above the overcharge voltage, thereby protecting the secondary battery from explosion or ignition. The leakage current value of the constant-voltage device is less than 0.05% of the capacity value of the secondary battery under the maximum charge voltage of the secondary battery, or the breakdown voltage of the constant-voltage device is higher than the maximum charge voltage of the secondary battery. Thus, the constant-voltage device rarely generates the leakage current even if the secondary battery has been charged with the maximum charge voltage.
摘要翻译：公开了具有用于防止二次电池过度充电的恒压装置的二次电池。恒压装置的击穿电压低于二次电池的爆炸或点火电压，因此即使二次电池的电压升高到过充电电压以上，放电操作也可能在二次电池分解或点燃之前发生，从而保护二次电池免受爆炸或点火。在二次电池的最大充电电压下，恒压装置的漏电电流值小于二次电池容量值的0.05％，或恒压装置的击穿电压高于最大充电电压的二次电池。因此，即使二次电池被充电最大充电电压，恒压装置也很少产生漏电流。

摘要： Disclosed is a secondary battery. The secondary battery includes a battery can serving as a positive electrode terminal or a negative electrode terminal of the secondary battery, an electrically conductive substrate provided at an outer portion of the battery can, and a nonconductive film interposed between the battery can and the electrically conductive substrate in order to insulate the electrically conductive substrate from the battery can, wherein the electrically conductive substrate is electrically connected to an electrode terminal having polarity opposite to that of the battery can. Safety of the secondary battery is ensured even if the secondary battery is subject to external parameters, such as penetration of a sharp tool (e.g. a nail or a drill tip), pressing force of a tool (e.g. a nipper), external impact, and exposure to the high temperature.
