Abstract
There is provided a reserve battery activated by shock application of hitting means and having good operational feature at low temperature, comprising: a frame forming exterior case; an ampoule disposed inside the frame, containing an electrolyte solution and formed of membrane at the portion where the hitting means applies hitting; two electrodes disposed above the ampoule and formed with two laminated ‘−’ and ‘+’ layers, a cathode layer and an anode layer, each of the layers having a hole at its center portion; a separator disposed between the two electrodes and including a center separator in the middle of the separator formed such that except for one side of the center separator, the other side of the center separator is cut, wherein the other side of the center separator comes into the ampoule by the hitting of a hitting means, and contacts with the electrolyte solution contained inside the ampoule so that the electrolyte solution is absorbed into the center separator being in contact with the electrolyte solution, and transferred to the two electrodes so as to activate the reserve battery.
