Abstract
An alkaline storage battery including a bottomed cell casing assembled as either one of positive and negative terminals, a closure cap assembly coupled with an opening of the cell casing in a liquid-tight manner as the other terminal to hermetically seal the interior of the cell casing and a generator element composed of positive and negative electrodes assembled within the cell casing, wherein a current collecting plate extended from either one of the positive and negative electrodes is welded at least at two spaced portions thereof with a bottom surface of the closure cap assembly to enhance mechanical strength and the vibration resistance property of the storage battery and to reduce internal resistance of the storage battery.
