采用计算机技术模拟材料的性能是新兴的研究领域。线性极化曲线是判断镍氢电池负极贮氢电极合金电化学性能的重要手段。通过对贮氢合金电极极化曲线模拟不仅可以从理论上研究各种因素如扩散系数、交换电流对电极性能的影响,而且还可以对实验结果进行验证。在此基础上还可以进一步发展神经网络系统,处理实验数据,获得相应动力学信息。本文根据电化学基本原理,在假设其他参数不变的条件下,分别考察了温度、交换电流、扩散系数、能量传递系数对极化曲线的影响,并初步分析了电极反应与腐蚀反应共存时的贮氢合金极化曲线特征。
The use of computer technology to simulate the performance of materials is an emerging field of research. The linear polarization curve is an important means to judge the electrochemical performance of Ni-MH battery negative electrode hydrogen storage alloy. Through the simulation of the polarization curve of hydrogen storage alloy electrode, not only can theoretically study various factors such as diffusion coefficient, exchange current on the performance of the electrode, but also can verify the experimental results. On this basis, the neural network system can be further developed to process experimental data and obtain corresponding kinetic information. In this paper, the influence of temperature, exchange current, diffusion coefficient and energy transfer coefficient on the polarization curves were investigated under the assumption of the other parameters, according to the basic principles of electrochemical. And the electrode reaction and corrosion reaction coexist Polarization curves of hydrogen storage alloys.
