US 5,707,758 A · Secondary battery

Abstract

A nonaqueous electrolytic secondary battery is formed by winding a thin-film positive electrode, a thin-film negative electrode, and a thin-film separator. A cap is arranged at the distal end portion of a pole bored through the cap and interposed between a nut and a disk-like portion of the pole through a ceramic washer being in contact with the nut and a ceramic patch being in contact with the disk-like portion. The ceramic washer and the ceramic patch consist of alumina or zirconia. For a bolt for interposing a bus bar or a conductive line to fix the bus bar or the conductive line, a female screw portion formed in the pole is arranged in a space of a spindle.
