NOVELTY - Stacked secondary battery (1) is formed by laying plate-shaped positive and negative electrodes (10, 20) one on other by separators (30), where collectors (11, 21) are disposed at front end of end facet of each of positive or negative electrodes as in direction relative to stacking direction and has active substance layer (23) formed on collector by applying slurry of particles of active substance with gap separating it from front end or electrode active substance layer is made to show thickness varying from front end toward inside.    USE - As a stacked secondary battery for portable equipment designed such as mobile phones, in the field of electric vehicles, electric bicycles, electric tools and power storages.    ADVANTAGE - The Stacked secondary battery provides cut end facet of each of electrodes which is smooth, and active substance adheres to collector with large adhering force, resulting to excellent charging/discharging characteristics of the battery. The active substance of the battery is prevented from coming off to large extent because of one or two molten and solidified sections formed in outer peripheral part of active substance layer of each electrode.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing stacked secondary battery involving forming at least either plate-shaped positive electrodes or plate-shaped negative electrodes by forming electrode active substance layer on each of electrodes by applying electrode active substance to metal foil having surface area greater than surface of electrode; cutting metal foil by irradiating laser beam; and removing part of electrode active substance layer running along the cut end facet of metal foil by thermal effect of laser beam to form molten and solidified section of electrode active substance; and sealing stacked secondary battery.    DESCRIPTION OF DRAWING(S) - The figure shows schematic illustration of stacked secondary battery.
