Abstract
The present invention relates to a separator for an electrochemical element having improved electrolyte wettability and an electrochemical element comprising the separator, in which a layer containing at least two binder polymers having different slopes on the frequency-storage modulus curve is formed on a surface of the separator, and with one of the binder polymers being concentratedly distributed on the surface of the separator, the separator and the electrode can be securely attached, and with the other binder polymer being permeated and coated onto a porous polymer substrate, electrolyte wettability can be enhanced.
