SEPARATOR CONTAINING COATING LAYER, METHOD FOR MANUFACTURING THE SEPARATOR AND BATTERY USING THE SEPARATOR

摘要

The present invention relates to a separation membrane comprising a coating layer with improved moisture tolerance, a manufacturing method thereof, and a battery using the same and, more specifically, to a separation membrane with improved moisture tolerance, a manufacturing method thereof, and a battery using the same, capable of representing heat resistance, strength, and adhesive power appropriate for a separation membrane by comprising a binder and an inorganic particle, reducing moisture contents inside the separation membrane by controlling a composition of a solvent forming a coating layer, and inhibiting increase of moisture contents under high humidity conditions by reducing a degree of moisture reabsorption.
