Electronic circuit model of NiOOH/Ni(OH){sub}2 electrode and electrochemical parameter analysis with genetic algorithm

摘要

An electronic circuit model of NiOOH/Ni(OH){sub}2 electrode was proposed and electrochemical parameters used in the model were optimized with genetic algorithm to simulate a charge curve in good agreement with the experimental curve. After theoptimization, several sets of the parameter values which could simulate the charge curves in good agreement with the experimental curve, were obtained. The convergence of the optimization with genetic algorithm was much faster than that with Monte Carlomethod. Sensitivities of the parameters were discussed. This study is a first step for characteristics analysis of battery materials in batteries without their overhauling.
