In the perspective of the energy transition, both market field and research world recognised the electric energy storage as the main medium for this purpose. Specifically speaking, lithium ion batteries are already one of the technologies of choice to accomplish the road-transport electrification. Indeed, this work is devoted to the study of a high energy density cell technology. The latter is the most important requirement for an Electric Vehicle, and it can be achieved thanks to a high voltage cathode combined with a very high capacity anode. In the light of this, in this work a Ni0.6Mn0.2Co0.2O2 electrode whose specific energy can reach 200 Wh/kg was chosen as cathode, while lithium metal foil has been exploited as anode since it shows the outstanding specific capacity of 3860 Ah/kg and the lowest electrochemical potential (-3.040 V vs SHE).
