WebElectrochemical performance of the graphene electrode can be split into two regimes depending on the number of graphene layers: (i) the corrosion-dominant regime and (ii) the lithiation-dominant regime. WebDec 1, 2013 · The graphite is stressed when some Na intercalates into it, thus the Na-GICs are unstable. In addition, based on the calculated energy barriers of the Li, Na and K ions jumps between the sites in the graphite, it can be deduced that the larger radius ions more smoothly diffuse in the graphite.
