MODELING OF NICKEL METAL HYDRIDE BATTERIES

A mathematical model of the discharge behavior of the nickel oxide/KOH /LaNi5 battery system is presented. The model shows great sensitivity to the kinetic parameters of the nickel oxide active material. The thi ckness and porosity of the battery system's electrodes are optimized i n terms of the specific energy and power of the system. Experimental r esults are presented which show some qualitative agreement with the di scharge curves predicted by the model. In this model, diffusion in the nickel oxide active material is neglected based on the findings prese nted in Appendix A.
