MANUFACTURING METHOD OF ELECTRODE FOR BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode for a battery with high precision in which a mixture paste is utilized with high yield, and variations in the width of unpainted portion leading directly to welding failure of the unpainted portion and a current collector and distortion of electrodes can be reduced.

SOLUTION: The manufacturing method of the electrode for battery comprises a painting process to coat continuously a mixture paste containing an active material on the core material made of continuous three-dimensional metal porous body. A pretreatment process in which an unpainted portion is provided by regulating the running position of the core material while interposing a part of the core material to make it in high density is provided before applying the painting process.
