Beschreibung
Zusammenfassung:	The present invention relates to electrode composite, comprising: 0.1 wt % to 20 wt % graphene; 0.1 wt % to 20 wt % carbon black and 2 wt % to 20 wt % binder, the rest being an active material of lithium transition metal oxide having a spinel structure, such as LiNi0.5Mn1.5O4 or LiMn2O4, or of a lithium transition metal compound having an olivine structure, such as LiFePO4, and presenting the electrode a thickness equal or greater than 40 μm. The invention also relates to a cathode comprising a current collector and disposed on the current collector said electrode composite, to a lithium ion cell and to a battery module comprising said cathode, and to a battery pack comprising at least one battery module for use in devices such as electric vehicles, portable electric devices and stationary energy storage devices for renewable sources. The invention also discloses a method for preparing said cathode.
