Abstract
The present disclosure provides an aromatic polyamide porous membrane having a uniform internal structure. The internal structure of the membrane is a three-dimensional network porous structure with micron-sized pores. The aromatic polyamide porous membrane of the present disclosure has good thermal stability and is especially suitable for a high energy density lithium-ion power battery, and greatly improves the thermal runaway temperature of the battery. The present disclosure further provides a method for preparing the membrane and a lithium secondary battery having the membrane.
