摘要:
【目的】为研究混合锂离子超级电容器(hybrid lithium ion supercapacitor,HLIC)的性能,分析多种干扰因素对其电化学与热特性的影响。【方法】首先建立HLIC电化学热耦合模型; 其次通过试验与数值模拟相互验证来证明模型的可靠性; 最后分析阳极活性材料颗粒粒径、充放电倍率、电芯结构状态对HLIC的电化学与热特性的影响,并通过建立核壳模型绘制核壳图,从微观的角度分析了阳极活性材料颗粒粒径对HLIC电化学性能的影响过程。【结果】HLIC在高倍率的条件下,减小粒径可使阳极活性材料颗粒锂化程度显著提高,10 C倍率下粒径15.5 μm与0.5 μm的单体相比,前者能量密度降低了63.14%,平均发热率增加了121.66%,最大温度上升了17.7 K; 而在低倍率的条件下,粒径对HLIC的性能影响不大,无须增加成本过分减小粒径,并且电芯在层压方向导热性较差,需要在层压方向上增加散热以保证其工作性能良好。【结论】本研究对各个场景所需的HLIC性能参数的选取具有一定的参考意义。
