Determination of the Lithium Ion Diffusion Coefficient in Graphite

Abstract: A complex impedance model for spherical particles was used to determine the lithium ion diffusion coefficient in graphite as a function of the state of charge (SOC) and temperature. The values obtained range from of 1.12 ϫ 10 Ϫ10 to 6.51 ϫ 10 Ϫ11 cm 2 /s at 25ЊC for 0 and 30% SOC, respectively, and for 0% SOC, the value at 55ЊC was 1.35 ϫ 10 Ϫ10 cm 2 /s. The conventional potentiostatic intermittent titration technique (PITT) and Warburg impedance approaches were also evaluated, and the advantages and disadvant… Show more

“…The curved diffusion pathway was chosen for Li in LiC 6 and Na in NaC 6 since it leads to a higher diffusion coefficient compared to the straight pathway, which will be discussed further below. Experimental diffusivity data [16][17][18][19][20][21][22][23][24] are included for comparison.…”

“…This model, due to its complexity, is not suitable for a model based estimation method such as Kalman filter. Not to mention that the nyquist plot can change a lot due to change of ambient temperature (Yu et al, 1999), SOC and external disturbances. …”
