BATTERY

摘要

Disclosed is a battery constituted by sealing in a battery case (14) an electrolyte and a group of electrodes (13) constructed by winding or laminating, with an intervening separator (2), a positive electrode plate (4) and negative electrode plate (8) formed by applying active substance layers (6, 10) to the surface of strip-shaped current collectors (5, 9); the locations of the separator (2) corresponding to at least the coating commencement and termination ends (6a, 10a) of the active substance layers (6, 10) or the ends of the current collectors (5, 9) are constituted by sections (2a) of improved physical properties with extra resistance to crushing.
