Manufacturing method of separator for electrochemical element
Document Type and Number:
Japanese Patent JP6317639
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a separator for electrochemical element capable of reducing the content of chlorine efficiently, and to provide a separator for electrochemical element manufactured by the manufacturing method, and having a high insulation resistance and less internal short circuit failure, and a long life electrochemical element including the same.SOLUTION: In a method of manufacturing a separator for electrochemical element by wet sheet making, a sheet is made using pure water, as the last cleaning water of a blanket in contact, at least, with a wet paper. The separator for electrochemical element manufactured by that manufacturing method, and an electrochemical element including the separator for electrochemical element are also provided.SELECTED DRAWING: None
