Voltage. A typical discharge-charge curve of a coimnercial iron/nickel oxide battery is shown in Fig. 25.3. The battery s open-circuit voltage is 1.4 V its nominal voltage is 1.2 V. On charge, at rates most commonly used, the maximum voltage is 1.7 to 1.8 V. 

Figure 24. The effects of hole lifetime and grain size on open circuit voltage and short circuit current. Solid curves are without and dashed curves are with space charge region recombination. The approximate relation Tp = 5.21 x 10 d was assumed to simulate grain boundary recombination effects.

Figure 10.10 Current-voltage curves for electrochemical storage processes, A or B. Ua and (/b are the redox potentials for the respective storage processes. Process A may be charged by the photodriven current-voltage curve P, whereas process B may not. In the photodriven I-V curve P, is the voltage corresponding to the point of maximum power, Pn ), and 4c and Pph are the short-circuit current and open-circuit photopotential respectively.
