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.

Abstract: A method of manufacturing an electrode for a battery comprises steps of preparing a substrate formed by a metal porous body having three-dimensionally continuous pores, a slurry mainly composed of active material powder to be filled into the pores of the substrate, a vessel for containing the slurry and a filling roller located to be at least partially dipped but not completely submerged in the slurry contained in the vessel, continuously supplying the substrate onto the filling roller so that the substrate is in contact with the filling roller in at least a point not being submerged in the slurry and rotating the filling roller in such a manner that the speed of outer peripheral surface of the filling roller facing the substrate is higher than the travel speed of the substrate thereby to fill the slurry into the pores of the substrate.
