Preparation method of absorbed glass mat separator by using plasma treatment

摘要

The present invention relates to a method for manufacturing an adsorption glass mat separator using a plasma treatment, and more particularly, preparing a glass fiber mat; And it relates to a method for producing an adsorption glass mat separator comprising the step of modifying the glass fiber mat (glass fiber mat) with a plasma. According to the present invention, if the surface of the separator is partially etched through the atmospheric pressure plasma etching, the AGM separator has a higher specific surface area and liquid retention than the existing separator, and has a low resistance, and thus is used in secondary battery fields such as general lead acid batteries and ultra batteries. Not only can it be used, but also has the advantage that it can be properly operated in virtually all batteries, such as redox flow battery, supercapacitor.
