Abstract
The present invention relates to a reserve battery allowing a voltage to quickly rise while being activated by an impact in a normal state in which electricity is not generated and, more specifically, to a reserve battery having a stacked electrode structure, the reserve battery improving the speed of an activation operation and generating a high voltage while being easily manufactured through a structure in which a main body case, instead of an ampoule of metal and glass materials, acts as an ampoule, a cover is attached through welding in a state of directly accommodating an electrolyte, and then a substrate having an anode and a cathode formed thereon is provided as a single layer or a plurality of layers, and a through film, which is broken by pressure and pushes the electrolyte toward the electrodes, is formed at the center of the cover.
