Abstract: An all-solid-state battery is provided therein with an ion-conducting binder between an electrode and a solid electrolyte film. The ion-conducting binder layer may fill a dead space physically contact-blocked between an electrode and a solid electrolyte film by liquefying plasticizer through heating such as temperature increase inside a battery to reduce interfacial resistance between the solid electrolyte film and the electrode. Further, a dead space of an interface between the solid electrolyte film and the electrode is filled by liquefying plasticizer to reduce surface contact non-uniformity between the solid electrolyte film and the electrode. Accordingly, interfacial resistance between the solid electrolyte film and the electrode can be reduced. Accordingly, ion conductivity of lithium ion can be increased and resistance can be reduced in the all-solid-state battery and a life performance of the battery can be improved. Moreover, the ion-conducting binder layer may include a predetermined amount of binder resin to further improve adhesion force between the solid electrolyte film and the electrode. In addition, the binder resin included in the ion-conducting binder layer reserves the liquefied plasticizer not to leak to an outside of the ion-conducting binder layer and improves adhesion force between the electrode and the solid electrolyte film.
