Title:
BATTERY AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3948121
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To further increase the battery capacity by making surplus spaces inside a battery can minimum.
SOLUTION: A diameter D of a winding core part 40 of a winding group formed by winding a band positive electrode plate 20 and a band negative electrode plate 22 through an outside separator 24 and an inside separator 26 is set at 2 mm or less. In this case, a positive electrode lead 52 is led out of a position, corresponding to a position outside at 2 mm of radius or more from the center of a winding group 16, and a negative electrode collector provided outermost of the winding group and the inner wall surface of the battery can 12 are made to electrically contact with each other through a conductive elastic member 62.
