The present invention relates to an electrode composite comprising 0.1 wt% to 20 wt% of graphene; 0.1 wt% to 20 wt% of carbon black; 2 wt% to the binder of 20 wt%, and the lithium transition metal oxide having a spinel structure as the remainder, for example, LiNi 0. 5 Mn 1 . 5 O 4 or LiMn 2 O 4 , or a lithium transition metal compound having an olivine structure such as LiFe 2 PO 4 , and the electrode composite has a thickness of 40 μm or more. The present invention also relates to a cathode module including a current collector and the electrode composite disposed thereon, a lithium ion battery, a battery module including the cathode, and a battery module including an electric vehicle, a portable electric device, And at least one battery module for use in the same device. The present invention also relates to a method of manufacturing the cathode. |
