WebSep 15, 2024 · This graphite stage corresponds to a lithiation degree of the graphite of 50% [42]. The fact that the peak is at a higher electrode SOC than 50 % is due to the fact that the silicon significantly contributes to the total electrode capacity but is not significantly delithiated in the SOC range above peak G 5 . WebDec 1, 2024 · From Figure 6, it also seen that the intensity changes are higher for the longest wavelengths (near infrared) during the early stages of lithiation, which are in line with the findings from Nieva et al. It should, however, be remembered that the input from the fiber only reflects the optical properties of the surface of the graphite particles ...
