BATTERY ELECTRODE PLATE AND ITS MANUFACTURING METHOD

Japanese Patent JP3838878

B2

PROBLEM TO BE SOLVED: To provide a battery electrode plate that is capable of performing three-dimensional current collection although thinly made and that has an excellent performance such as that it does not generate expansion at the rolling process or internal short-circuiting, while having a structure of low cost and high mass producibility, and a manufacturing method of producing the battery electrode plate.
SOLUTION: In the core material 1 applied in filled state with a mixture made primarily of active material 2, the rows of the bent protrusion section 8, which are formed with the first and the second bent protrusion section 4, 7 of a strip of fancy book shape respectively protruding alternately in both directions on the front and the rear of the metal sheet 3, and which are formed in a direction X of the metal sheet 3, have a shape in which plural rows are arranged along the other direction Y which crosses at right angles the direction X of the metal sheet 3, by interposing the flat section 9 of a prescribed width. This battery electrode plate is manufactured by either of a reciprocating method or a rotary method by continuous press, or by an electrolytic precipitation method.
