Thermodynamic parameters for nickel-cadmium (NiCd) and nickel-hydrogen (NiH[sub 2]) batteries are calculated for temperatures ranging from 273.15 K (0 C) to 373.15 K (100 C). For both systems, the authors list equilibrium and thermoneutral voltages for the cells, and in the case of the NiH[sub 2] battery, these data are provided for hydrogen fugacities ranging from 0.01 to 100 (atm) to simulate the full discharged and charged states. The quality of the input thermodynamic data is assessed and the effect of assuming different cell reactions is analyzed.
