PARTIALLY CROSSLINKED ADHESIVE-SUPPORTED POROUS FILM FOR BATTERY SEPARATOR AND ITS USE

摘要

An electrode/porous film assembly, a method for preparing a battery by containing the electrode/porous film assembly, and a battery prepared by the method are provided to prevent the slip movement between an electrode and a porous film(separator) when a battery is prepared, thereby improving the efficiency of the preparation of a battery. An electrode/porous film assembly is prepared by crosslinking the partially crosslinked adhesive of an electrode/porous film laminate by the reaction of the unreacted functional group of a reactive polymer and a multifunctional compound and adhering the electrode to a porous film, wherein the electrode/porous film laminate comprises a reactive polymer having a functional group in a molecule; a porous film which comprises a porous film base where the partially crosslinked adhesive having a gel fraction of 5-99 % partially crosslinked by a crosslinking adhesive composition containing a multifunctional compound crosslinkable with the functional group of the reactive polymer is supported; and an electrode.
