Beschreibung
Zusammenfassung:	An electrode binder for a lithium secondary battery, and an electrode and a lithium secondary battery, including the electrode binder. The electrode binder includes: a cellulose-based graft copolymer grafted with a compound having an ion-hopping site; and a polyacrylate-based polymer having an anionic group via an exchange with a cation. By including the electrode binder in at least one of the positive electrode and the negative electrode, it is possible to provide a lithium secondary battery capable of enhancing fast charging/discharging behavior efficiency of the electrode by reducing electrode resistance generated inside the electrode during charging/discharging.
