Lithium bis(pentafluoroethanesulfonyl)imide, Li[N(SO2C2F5)2], a typical fluorochemical aimed at better electrochemical performance of battery electrolytes, in superheated water was studied for its waste treatment. When Li[N(SO2C2F5)2] was reacted in pure superheated water at 300 °C, little F– ions were produced. In contrast, complete mineralization of the fluorine, sulfur, and nitrogen atoms in Li[N(SO2C2F5)2] was achieved when the reaction was performed in the presence of KMnO4. Specifically, when Li[N(SO2C2F5)2] was treated for 18 h with 158 mM of KMnO4, the F– and SO42– yields were 101 and 99%, respectively, and the sum of the NO3– and NO2– yields was 101%. In the gas phase, trace CO2 was detected and no CHF3, which has high global warming potential, was formed. Furthermore, the fluorine, sulfur, and nitrogen atoms in the analogues K[N(SO2C4F9)2] and K[N(SO2CF2)2CF2] also underwent complete mineralization using the same approach.

使用过热水有效矿化双（五氟乙磺酰）亚胺锂及相关电解质含氟化合物
双(五氟乙磺酰)亚胺锂Li[N(SO 2 C 2 F 5 ) 2 ]是一种典型的含氟化合物，旨在提高电池电解质的电化学性能，研究了其在过热水中的废物处理。当Li[N(SO 2 C 2 F 5 ) 2 ]在300℃的纯过热水中反应时，产生很少的F-离子。相反，当反应在KMnO 4存在下进行时，Li[N(SO 2 C 2 F 5 ) 2 ]中的氟、硫和氮原子实现完全矿化。具体来说，当Li[N(SO 2 C 2 F 5 ) 2 ]用158 mM KMnO 4处理18小时时，F -和SO 4 2-产率分别为101％和99％，并且F - 和SO 4 2- 产率分别为101％和99％。 NO 3 –和NO 2 –产率为101%。在气相中，检测到微量CO 2 ，并且没有形成具有高全球变暖潜能的CHF 3 。此外，类似物K[N(SO 2 C 4 F 9 ) 2 ]和K[N(SO 2 CF 2 ) 2 CF 2 ]中的氟、硫和氮原子也使用相同的方法经历了完全矿化。
