摘要： Disclosed is an apparatus for protecting a secondary- battery, in which, when the secondary battery such as a lithium-ion secondary battery is exposed to high temperature exceeding a working range due to a change in external environment, external impacts, and so on, or heated due to spontaneous generation of heat caused by internal defects, the secondary battery is discharged.

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，恒压器件的漏电流值小于二次电池的容量值的0.05％，或者恒压器件的击穿电压高于最大充电电压的二次电池。因此，即使二次电池已经充电了最大充电电压，恒压装置也很少产生漏电流。

摘要： Disclosed is a battery safety device adapted to form an electrical circuit when compressed by a predetermined pressure or higher and convert the charged state of a battery to the discharged state, a battery having the safety device, and a method for adjusting the safety of a battery by converting the charged state of the battery to the discharged state, before the battery is damaged by a pressure, through an electrical circuit formed on a safety device by means of the pressure. The safety device has a first metal plate, a second metal plate, and a pressure-sensitive conducting film interposed between both metal plates and adapted to exhibit electrical conductivity when a predetermined pressure or higher is applied. The first and second metal plates are electrically connected to the positive and negative electrodes of the battery, respectively. The safety device connected to a battery prevents the battery from being damaged or at least from igniting or exploding, even when an external impact caused by a pressure, a nail, or a nipper or an external pressure is applied to the battery, by conducting the current of the battery to the safety device and discharging the battery before the battery is damaged by the external impact or external pressure.
