摘　　要：电池模拟是预测电池性能和指导电池材料设计的重要手段。基于Newman模型的传统模拟对于描述锂离子电池电化学性能已非常成熟,值得注意的是,其本身也存在材料均一化假设等缺点,并且随着材料的纳米化,这种模拟显得更加不足。从层析实验手段(FIB/SEM以及X-ray断层技术)入手,进而讨论基于介观结构的建模手段,以及相应的数值分析研究进展状况。Battery simulation is an important means of predicting battery performance and guiding battery material design. The traditional simulation based on the Newman model is very mature for describing the electrochemical performance of lithium-ion batteries. It is worth noting that there are also shortcomings such as material homogenization assumptions, and this simulation is even more insufficient with the nanocrystallization of materials. Starting with chromatographic experiments (FIB/SEM and X-ray tomography), the mesoscopic structure-based modeling methods and the corresponding numerical analysis research progress were discussed.
