Disclosed are a safety device and a secondary battery using the same. The safety device includes a voltage sensitive heating device generating heat when a voltage difference between both ends thereof exceeds a predetermined voltage level and a temperature sensitive device having a reversible current ON/OFF function according to a temperature. The temperature sensitive device is coupled with the voltage sensitive heating device such that the temperature sensitive device detects the heat generated from the voltage sensitive heating device.
L'invention concerne un dispositif de sécurité et un accumulateur utilisant ledit dispositif. Ledit dispositif de sécurité comprend un dispositif de chauffage sensible à la tension, produisant de la chaleur, lorsqu'une différence de tension entre les deux extrémités dépasse un seuil de tension prédéterminé et un dispositif sensible à la chaleur présentant une fonction marche-arrêt du courant réversible en fonction de la température. Le dispositif sensible à la température est couplé au dispositif de chauffage sensible à la tension, de sorte que le dispositif sensible à la température détecte la chaleur produite à partir du dispositif de chauffage sensible à la tension.
