摘要
In this paper, a mathematical model for the cycling electrochemical capacity of hydride electrodes was deduced on the basis of activation and degradation of hydride materials. A cycle life model was deduced on introducing the activation and degradation factors into the electrochemical polarization equation which included concentration polarization, phase transformation polarization and electrochemical polarization. Experimental data on the TiNi hydride electrode were in good agreement with the deduced model. From this model, various factors affecting the cycle life were identified and the methods to enhance the cycle life were suggested.
