Figure 7.61a shows three well-dened reduction peaks labelled as A, B and
C; and fourth and fth peaks labelled as D and E are observed as shoulder
at 1.0 V, and as a very large wave, respectively. Integrating current against
time, the same sequence of redox reactions is demonstrated in Figure 7.61b
as voltage versus Li

. This shows the domain limits for the successive elec-
tron plus the ion insertion process appears at x = 0.5, 2, 3, 4 and 12. From
Figure 7.61c, it is evident that the Li intercalation into the system is reversible
between 1.3 and 3.0 V with three sets of redox reactions (or) i ...
