Incremental Capacity Analysis of Half Cell

The monoclinic lithium vanadium phosphate Li3V2(P04)3 exhibits an excellent reversibility when the charge extracted is limited to the value equivalent to two Li per formula unit. The extraction of the last lithium is observed at a potential greater than 4.6 V vs. Li /Li and involves a significant overvoltage [35]. In Li cV2(P04)3, the redox couple takes place in the range x= 1-3. 

Both voltage profile and incremental capacity are shown in Fig. 13.13. The experimental titration curve for LiV2(P04)3 displays three regions, which span in the composition ranges Xi= 0-0.5, X2 = 0.5-1, and 3 = 1-2 in Li(3 ,)V2(P04)3, 

Electrochemical potential spectroscopy was successfully used to smdy the differential capacity dQ/dV as a function of potential in the sihcon nanowires (SiNw) that provides information about the structural transformations during Uthiation and deUthiation. The voltage vs. capacity profile and the corresponding
