Title:
A manufacturing method and a manufacture device of the separator for electrochemistry elements
Document Type and Number:
Japanese Patent JP5975815
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing apparatus of the separator for an electrochemical element, in which a coating component exists uniformly on the principal surface, by preventing occurrence of such a part as the coating liquid does not exist or only a little amount of which exists on the principal surface of a porous sheet.SOLUTION: When coating the principal surface of a porous sheet with a coating liquid by a manufacturing method and a manufacturing apparatus of the separator for an electrochemical element, occurrence of such a part as the coating liquid does not exist or only a little amount of which exists on the principal surface of a porous sheet can be prevented (in other words, the principal surface of a porous sheet can be coated uniformly with a coating liquid). When removing a solvent from a porous sheet where the principal surface thus prepared is coated uniformly with a coating liquid, the separator for an electrochemical element, in which a coating component exists uniformly on the principal surface, can be manufactured.
