【摘要】：采用SLMP(stabilized lithium metal powder)研究预嵌锂过程对锂离子电容器性能的影响.通过高倍率光学显微镜研究加入电解液后预嵌锂负极的变化;通过对比不同嵌锂含量对半电池与全电池性能的影响,分析得出含量对锂离子超级电容器的容量、能量密度和功率密度的影响,发现超稳态锂粉的质量分数在14%左右时,锂离子电容器可以获得较好的性能.
[Abstract]:The effect of pre-intercalated lithium on the performance of lithium ion capacitor was studied by SLMP(stabilized lithium metal powder. The change of pre-intercalated lithium negative electrode after adding electrolyte was studied by high-rate optical microscope, and the capacity of lithium ion supercapacitor was analyzed by comparing the effect of different lithium intercalation content on the performance of half-battery and the whole battery. Under the influence of energy density and power density, it is found that when the mass fraction of ultra-steady lithium powder is about 14%, the lithium ion capacitor can obtain better performance.
