<p>The present invention relates to a reserve battery having excellent low-temperature properties and, more specifically, to a reserve battery having excellent low-temperature properties which are activated when hit by an explosion device, comprising: a frame which forms the exterior thereof; an ampoule unit which is positioned inside the frame and stores an electrolyte; two "+" and "-" electrodes which are positioned on the upper side of the ampoule unit and in which a cathode layer and an anode layer are formed in a stacked shape so as to form a hole in the center thereof; and a separator which is positioned between the two electrodes, includes a center having a cut part and of which one side is not cut, and is connected to the outside. In addition, the reserve battery can be enabled by breaking a breaking groove using the force generated from a balance weight through a setback so as to transfer the electrolyte stored inside the ampoule unit to the two electrodes when the explosion device and the like cannot operate due to a malfunction.</p> |
