POUCH-SHAPED SECONDARY BATTERY INCLUDING PRESSURE SENSING DEVICE CONFIGURED TO MEASURE INTERNAL PRESSURE

POUCH-SHAPED SECONDARY BATTERY INCLUDING PRESSURE SENSING DEVICE CONFIGURED TO MEASURE INTERNAL PRESSURE [0002] The present invention relates to a pouch-shaped secondary battery including a pressure sensing device having one side located in the case and the other side located outside the case, the pressure sensing device being configured to accurately measure pressure in the pouch-shaped secondary battery. Consequently, it is possible to predict abnormality of the pouch-shaped secondary battery or lifespan of the pouch-shaped secondary battery.
