Abstract
The present invention relates to: an electrode assembly having an inorganic porous coating layer formed on the surface of one electrode of an anode and a cathode and having an organic porous coating layer formed on the surface of the other electrode, and since these porous coating layers exhibit a separator function, the electrode assembly has a more improved heat resistance and safety at high temperature without requiring a separate separator; a manufacturing method therefor; and an electrochemical element comprising the electrode assembly.
