The present invention relates to a rechargeable lithium battery including composite graphene-containing binder, and it is high-capacity, high-speed chargeable. When using a nanocomposite consisting of the graphene dispersion in the polymer according to the present invention as a binder of the negative electrode material mixture, the performance of the composite binder improved by despite the large volume change of the negative electrode active material in charging and discharging process, and the active material and between the total and the home of the bonding force it can be stably maintained, so that the binder itself has a high conductivity can be prepared a lithium secondary battery of the electrical performance improvement capacity.
