概要 Since the late 1990s, lithium bis(pentafluoroethanesulfonyl)imide, Li[N(SO2C2F5)2], has been widely studied as an electrolyte component for use in rechargeable lithium-ion batteries, lithium batteries, lithium−air batteries and all-solid-state lithium batteries. While Li[N(SO2C2F5)2] contributes to the safety of such batteries, it falls into the category of per- and polyfluoroalkyl substances (PFASs). Under these circumstances, waste-treatment technologies that afford complete decomposition of Li[N(SO2C2F5)2] and its analogues are needed. Herein we examined the mineralization of Li[N(SO2C2F5)2] in superheated water. We also applied our approach to two potassium salt analogues, one bearing [N(SO2C4F9)2]- and one bearing cyclic [N(SO2CF2)2CF2]-, which are also used as electrolytes and other applications.
