Webto correspond with the well-known graphite staging mechanism. Therefore, a high-power 2.6 Ah graphite/LiNiCoAlO2 cell (Sony US18650VTC5) is cycled at di erent, well-defined state-of-charge (SOC) ranges, covering the di erent graphite stages. An open circuit voltage model is applied to quantify the loss mechanisms (i) and (ii). WebApr 1, 2024 · The graphite layers are stacked in three different modes: hexagonal, Bernal, and rhombohedral, marked as AA, AB, and ABC-stacking, respectively, as shown in Fig. 4 [44]. The layer-layer distance ( Iz) is 3.35 Å.
