<p>An ulatraminiaturized reserve battery cell the whole size of which is as small as several millimeters and which includes small battery components the sizes of which are several micrometers and is fabricated by micromachining for machining a mechanical structure to a very small size, so as to complement the drawbacks of existing large reserve battery cells which can be hardly used for small electronic systems. An electrolyte jar and other battery components are realized by using materials such as silicon, nickel, copper, and aluminum. The electrolyte jar containing an electrolyte in contact with the battery cell has a membrane structure having a smaller thickness than that of the periphery. Only at the activation, the structure is broken to ensure sufficient impact resistance strength in normal use and to activate the battery with small power.</p> |
