摘要
以不同负极材料为研究对象,对Li Fe PO4/C体系动力锂离子电池的高温储存及高温循环性能展开研究,通过X射线衍射(XRD)和扫描电镜(SEM)等分析方法对高温储存前、后负极片的物相组成和微观形貌等进行了对比研究。研究结果表明,负极材料的物理特性变化是影响电池高温储存及高温循环性能的主要因素。
Different anode materials of lithium-ion battery（Li Fe PO4/C） were studied. XRD,EIS,SEM and FTIR analysis shows that phase composition and microstructure of negative electrodes changed before and after high temperature storage. Results show that the physical properties of the cathode material were a major factor that impacts on battery temperature storage and temperature cycle performance
