Voltage capacity curves

The second cycle charge/discharge curve for the Li/composite polymer electrolyte/ FeS2 cell is shown in Figure 10.9. Region b in the voltage/capacity curve in the figure... 

The preparation by hydrothermal method and properties of nanotubes of Na2Ti30y have been reported [25]. In contrast to the Na2Ti30y bulk powder which exhibits a two-phase plateau at 0.3 V [26], the nanotube exhibits a sloping voltage-capacity curve, which suggests a pseudocapacitive mechanism. In addition, the nanotubes exhibit better rate capability than the bulk powder.

Figure 38 shows discharge curves [372] for the LiAl/LiCl-KCl/FeS battery. It can be noticed that the discharge appears to take place at a single potential (1.6 V versus Li), yielding only one plateau in the voltage capacity plot.
