摘要
通过实验和参数辨识,确定了针对LiNi_(0.5)Mn_(1.5)O_4体系电池所需要的模型参数,建立了适用于该体系的变固相扩散系数模型。该模型能很好地对LiNi_(0.5)Mn_(1.5)O_4的放电过程进行模拟。通过对电池内部的过电位进行分析,对电池性能的限制因素进行了说明。
By adopting experiment and parameter recognition method,it was confirmed that a larger number of parameters whicb needed for the model of new system could setup a suitable model that involved variable solid-state diffusivity （VSSD）. The model was used to simulate performance of LiNi0.5Mn1.5O4 electrodes. The model was validated that it could be used to better simulate the discharging processes of LiNi0.5Mn1.5O4, by analyzing the over potential of battery and explaining its limiting factors.
