Graphite lithiation potential
WebFirst, it is observed that blocking conditions are achieved in all instances upon the full lithiation of the NCM particles through a potential hold of 1 h at 2.55 V vs. Li + /Li. WebMar 1, 2024 · Taking into account the electrochemical potentials of Si and graphite, the lithiation behavior should have exhibited two plateaus, such as 0.4 V for Si and 0.05 V for graphite. However, voltage profiles of the 1st lithiation at a constant current mode typically have a single plateau.

WebFeb 23, 2024 · The lithiation process can be separated into seven stages, as labelled by L1-L7 in Fig. 6a1. From the figure, it can be seen that the lithiation starts with Si in stage L1 at electrode potentials >0.225 V, and graphite becomes dominant in the lithiation reaction in the later stages after the potential drops below 0.225 V.
