研究了商用石墨KS6 TIMCAL在n -甲基- n -丁基吡啶二（三氟甲磺酰基）亚胺（PYR14TFSI）和n -甲基- n -丙基吡啶二（氟磺酰基）亚胺（PYR13FSI）两种不同离子液体中固体电解质界面相（SEI）的形成。研究了碳酸丙烯酯（VC）在离子液体电解质中的作用。为了监测SEI形成过程中电极/电解质（IL）界面的变化，我们利用了原位傅里叶变换红外光谱（FTIRS）。在室温下进行的调查结果呈现在这份手稿中。
The solid electrolyte interphase (SEI) formation on commercial graphite, KS6 TIMCAL, in two different ionic liquids, N-methyl-N-butyl pyrrolidinium bis (trifluoromethansulfonyl) imide (PYR14TFSI) and N-methyl-N-propylpyrrolidinium bis (fluorosulfonyl) imide (PYR13FSI) has been investigated. The role of the vinylene carbonate (VC) addition to the ionic liquidbased electrolyte has also been studied. To monitor the change at the electrode/electrolyte (IL) interface during the SEI formation, we took advantage of the in situ Fourier transform infrared spectroscopy (FTIRS). The results of the investigation performed at room temperature are presented in this manuscript.
