锂离子电池析锂量化及模型研究
Quantitative characterization and modeling of lithium plating in lithium-ion batteries
摘要
Abstract
In this study,an electrochemical-thermal coupled model was developed to characterize the behavior of lithium-ion batteries,and its accuracy was validated through comparison with experimen-tal data.Furthermore,the effects of solid electrolyte interphase(SEI)layer growth and lithium plat-ing side reactions on battery performance and lifespan were further incorporated,and a lifetime pre-diction model was established.Besides,the evolution of the morphology of anode surface was investi-gated during cycling.Combined with inductively coupled plasma optical emission spectroscopy(ICP-OES)experiments,a quantitative analysis of capacity degradation induced by lithium plating was con-ducted,and the aging rate of lithium plating side reactions was determined via simulation modeling.By comparing the simulation results with experimental data under different C-rates at 0 and 25℃,it is found that the root-mean-square error(RMSE)of the model remains below 6.48％in predicting the remaining available capacity,and the model successfully reproduces the capacity fade phenomena.关键词
