Abstract
Provided are a micro-porous hybrid film and a method for preparing the same, and more particularly, a micro-porous hybrid film capable of improving reliability of a battery by simultaneously improving thermal stability at a high temperature and water properties, and a method for preparing the same. In addition, the present invention relates to a micro-porous hybrid film suitable for a separator of a high capacity/high output lithium secondary battery capable of increasing production stability, long term stability, and performance of the battery by improving adhesive force between a micro-porous film and a coating layer and permeability and minimizing a water content by the coating layer.
