【摘要】：采用SLMP(stabilized lithium metal powder)研究預(yù)嵌鋰過程對鋰離子電容器性能的影響.通過高倍率光學(xué)顯微鏡研究加入電解液后預(yù)嵌鋰負(fù)極的變化;通過對比不同嵌鋰含量對半電池與全電池性能的影響,分析得出含量對鋰離子超級電容器的容量、能量密度和功率密度的影響,發(fā)現(xiàn)超穩(wěn)態(tài)鋰粉的質(zhì)量分?jǐn)?shù)在14%左右時,鋰離子電容器可以獲得較好的性能.
[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.
