Abstract

The present invention relates to a separation film for an electrochemical device having excellent mechanical strength by substantially comprising inorganic substance particles an electrochemical device including the same and a method for using a high internal phase emulsion (HIPE) when manufacturing the separation film. The separation film for an electrochemical device according to the present invention has high resistance against temperature increases or external shocks and enables a lithium ion and the like to move smoothly by having fully formed pores. In addition the electrochemical device employing the separation film has remarkably improved stability and performance.
