INTRODUCING METHOD OF SULFUR-CONTAINING FUNCTIONAL GROUP, METHOD OF MANUFACTURING FOR SEPARATOR FOR BATTERY, AND SEPARATOR FOR BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently introducing a sulfur-containing functional group, with high reactivity, the manufacturing method of a separator for a battery, and a separator for a battery. SOLUTION: The introducing method of the sulfur-containing functional group comprises contacting an objective material having moisture with a mixed gas containing fluorine gas and sulfur-containing compound gas. The manufacturing method of the separator for the battery comprises contacting a fiber sheet having moisture with the mixture gas containing fluorine gas and sulfur- containing compound gas. The separator for the battery comprises the sheet manufactured by the above process.
