Figure 1 presents results on the beneficial effect of a new electrolyte solvent on the cycling behavior of the lithium storage alloy Sn2Co. The influence of the adapted electrolyte may become even more clearly by taking a look at the cumulated charge losses (Fig. 22). It should be noted that this new electrolyte component is not able to suppress solvent co-intercalation into graphite [37], emphasizing the above-mentioned different requirements on the electrolyte.

Figure 8. EG conversion to CO2 by Ag(II) in HNO3 plotted against cumulative charge (integrated current). Experiments were conducted at 24% i (336mA and 27°C), 40% i (673 mA and 33°C), and 58% iL (1346 mA and 42°C). The electrode separator was a Nafion 117 cation-exchange membrane.

Figure 12. EG conversion to CO2 by Co(III) in H2SO4 plotted cumulative charge. Experiments correspond to Figure 11.

The inflexion points or (quasi-) current plateaus in Figures 2(a) and 3(a) of Section III.l also prove to originate from the phase transition, from the comparison between the cumulative charges during the CT experiments and during the measurement of electrode potential. Furthermore, the origin of the shoulders and of the more than one local maxima in Figures 2(b) and 3(b) is, undoubtedly, the phase transition. 

Next let us examine the current-potential relation with increasing lithium intercalation/deintercalation time. For this purpose, the values of current at the times when various amounts of cathodic or anodic charge have passed (open symbols in Figures 9a-e) were obtained as a function of potential step. For example, in order to determine the open circle A in Figure 9(a), the cumulative charge vs. time plot is first...
