Microporous membrane, and preparation method therefor and application thereof

Abstract

The present application belongs to the technical field of separator material preparation, in particular to a microporous membrane, and a preparation method therefor and an application thereof. The microporous membrane includes a polymer and an ionic liquid. Based on a total mass of the microporous membrane, the microporous membrane includes 0.01 wt %-5 wt % of the ionic liquid. By introducing an appropriate amount of the ionic liquid into the microporous membrane, the ionic liquid can be continuously or discontinuously adsorbed on surfaces of fibrils inside the microporous membrane. This can not only eliminate internal static electricity, better avoid the reduction of ionic conductivity, but also alleviating the problem of static electricity accumulation in the microporous membrane, and meanwhile enables the microporous membrane to have low
