“…This implies that in electrochemical systems that exhibit hysteresis, the potential cannot be used as a means of estimating the SOC. In addition, relating z to the ratio of the activities of the oxidized and reduced species, 32 and in turn relating them to the potential using Nernstian thermodynamics, [13][14][15] would not be appropriate for such systems. Figure 6 shows the boundary curves and the discharge scanning curves for the nickel hydroxide electrode.…”

The nickel hydroxide electrode is known to exhibit a stable hysteresis loop, with the potential on charge being higher than that on discharge at every state-of-charge ͑SOC͒. What we show here is that this loop created during a complete charge and discharge ͑i.e., boundary curves͒ is not sufficient to define the state of the system. Rather, internal paths within the boundary curves ͑i.e., scanning curves͒ can be generated that access potentials between the boundary curves. The potential obtained at any SOC, as well as how the material charges and discharges from that point, depends on the cycling history of the material. The implication of this phenomenon is that the potential of nickel-based batteries cannot be used as an indication of the SOC of the cell. Analysis of the boundary and scanning curves suggest that the electrode consists of a number of individual units or domains, each of which exhibits two or more metastable states. The cycling behavior of the nickel hydroxide electrode is discussed within the context of previously developed theoretical arguments regarding domain theory. Although the specific cause for the metastability in each domain is not understood, considerable insights are provided into the history-dependent behavior of the nickel hydroxide electrode. Finally, an empirical procedure is developed to predict the scanning curves based on the boundary curves.

“…Both show an increasing trend as the surface closest to the anode is approached (i.e., bed depth approaching zero), because the overpotential is highest at this surface. [18][19][20][21] show similar comparisons for the nitrate system. The kinetic parameters used are shown in Table 4.…”

Lithium batteries are increasingly being considered for installation as power sources in electric and hybrid vehicles, because of their high specific energy and power. To effectively size the vehicle Rechargeable Energy Storage System, it is very important to be able to mathematically model their behaviour. Battery modelling is also very useful for on-line management of electric and hybrid vehicles. This paper presents a dynamic model of lithium batteries based on experimental tests on high power Lithium-polymer models. The results can be adapted, with suitable parameter evaluation, to other lithium batteries as well.
