An electrode assembly with enhanced interlayer binding force between a separator and an anode

摘要

The present invention relates to an electrode assembly for an electrochemical device, and the electrode assembly includes an electrode and a separator. The electrode is a cathode and an anode, and the separator is interposed between the cathode and the anode. In addition, at least one electrode, that is, the negative electrode and / or the positive electrode faces a porous coating layer formed on at least one surface of the separator, and the porous coating layer includes inorganic particles and a binder polymer resin. In the electrodes and porous coating layers facing each other, the affinity of the binder polymer resin (first polymer resin) included in the electrode and the binder polymer resin (second polymer resin) included in the porous coating layer satisfies a specific formula. will be.
