Abstract

Disclosed are a separator for an electrochemical device, comprising a porous base membrane, a coating layer disposed on at least one side of the porous base membrane and at least one channel for ionic flow, wherein the coating layer comprises at least one organic material with, for example, a core-shell structure that melts when the electrochemical device is overheated to a temperature that is higher than the melting point of the at least one organic material to block the at least one channel for ionic flow; as well as an electrochemical device comprising the separator and a method for making the separator.
