A secondary battery module includes a plurality of battery cells aligned in one direction, a plurality of insulation sheets between the plurality of battery cells, the insulations sheets including aerogel for blocking heat transfer between the plurality of battery cells, and a housing fixing the battery cells and the insulation sheets. The secondary battery module may prevent or retard generation of heat or ignition from a cell within the module from propagating to adjoining cells.

Secondary battery module

The present invention relates to a separator comprising a coating layer and a battery using the same, the separator having improved adhesive force to an electrode, thereby minimizing the rate of thickness change. More specifically, the present invention relates to a separator having a coating layer on one or both surfaces of a base film, the coating layer comprising an acrylic-based copolymer having a glass transition temperature of less than or equal to 80&#xb0; C. and an inorganic particle, so as to have improved adhesive force and heat resistance, thereby being applicable in electrochemical batteries of various sizes and having excellent thermal stability and dimensional stability.
