研究了双（氟磺酰基）酰胺阴离子（FSA阴离子）在高取向热解石墨（HOPG）电极上的嵌入/脱嵌行为。使用拉曼光谱和X射线衍射测量来验证阶段1 FSA-石墨插层化合物的形成，其具有0.78 nm的廊道高度。HOPG在LiFSA碳酸盐基电解质中显示出约60 mA h g（-1）的可逆容量。讨论了FSA阴离子与双三氟甲磺酰胺阴离子的区别。(C)2015年电化学学会。All rights reserved.
The intercalation/de-intercalation behavior of the bis(fluorosulfonyl) amide anion (FSA anion) at a highly oriented pyrolytic graphite (HOPG) electrode in an carbonate-based electrolyte solution was investigated. Raman spectroscopy and X-ray diffraction measurements were used to verify the formation of a stage-1 FSA-graphite intercalation compound, which had a gallery height of 0.78 nm. The HOPG showed approximately 60 mA h g(-1) of reversible capacity in a LiFSA carbonate-based electrolyte. The difference between the FSA anion and bis(trifluoromethanesulfonyl) amide (TFSA) anion was also discussed. (C) 2015 The Electrochemical Society. All rights reserved.
