Title:
MANUFACTURE OF SECONDARY BATTERY AND CURRENT COLLECTING BODYFOR POLE PLATE AND CURRENT COLLECTING BODY FOR POLE PLATE
Document Type and Number:
Japanese Patent JPH08329951
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance current collecting efficiency, and lengthen a service life of a battery by constituting proper holes according to a joining characteristic of a reactive substance of a peripheral part and a central part of a current collecting body, in the current collecting body. SOLUTION: An interval and a hole diameter of holes arranged in a current collecting body are set and arranged in the following relationship so that a hole opening rate of a peripheral part becomes higher than a central part of the current collecting body for a pole plate. Px ≠ a constant length. Py ≠a constant length. ϕ = a constant length. (Where, Px is an interval of respective holes arranged on the X axis of the current collecting body, and Py is an interval of respective holes arranged on the Y axis of the current collecting body, and ϕ is a hole diameter of respective holes arranged in the current collecting body).
