Title:
ELECTRODE PLATE FOR BATTERY AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH08329954
Kind Code:
A
Abstract:

PURPOSE: To provide an electrode plate for a battery capable of lengthening the cycle life and preventing short circuit by giving a foamed metal plate the specified properties in the electrode plate constituted by filling an active material in a current collector made of the foamed metal plate having three- dimensional net structure.

CONSTITUTION: Such a property that the density of a skeletal part 23a in the central part in the thickness direction is higher than that of both side parts 23b in the thickness direction is given to a foamed metal plate. A pore 22a positioned in the central part in the thickness direction is largely compressed in the thickness direction than a pore 22b positioned on both sides in the thickness direction. The foamed metal plate is manufactured in such a way that more pores are formed in the cental part so that a pasty active material is filled from the both sides of a foamed metal strip 2 to the central part in the thickness direction, the active material is attached on both sides of the foamed metal strip 2 with rollers 6a, 6b, dried, then compressed with first press rollers 10a, 19, and compressed again with second press rollers 11a, 11b.
