What is Lithium bis(trifluoromethanesulfonyl)imide?
'''Lithium bis(trifluoromethanesulfonyl)imide''' (LiTFSI) s a [[hydrophilic]] [[salt]]. Its [[chemical formula]] is LiC<sub>2</sub>F<sub>6</sub>NO<sub>4</sub>S<sub>2</sub>.<ref>{{Cite web|last=PubChem|title=Lithium bis((trifluoromethyl)sulfonyl)azanide|url=https://pubchem.ncbi.nlm.nih.gov/compound/3816071|access-date=2020-09-19|website=pubchem.ncbi.nlm.nih.gov|language=en}}</ref> It is commonly used as a source of [[lithium]] [[Ion|ions]] in [[Electrolyte|electrolytes]] for [[Lithium-ion battery|lithium-ion batteries]]. It is an alternative to the commonly used [[lithium hexafluorophosphate]]. It is made up of one lithium [[cation]] and a [[bistriflimide]] [[anion]].<ref>{{Cite journal|last1=Kalhoff|first1=Julian|last2=Bresser|first2=Dominic|last3=Bolloli|first3=Marco|last4=Alloin|first4=Fannie|last5=Sanchez|first5=Jean-Yves|last6=Passerini|first6=Stefano|date=2014|title=Enabling LiTFSI-based Electrolytes for Safer Lithium-Ion Batteries by Using Linear Fluorinated Carbonates as (Co)Solvent|url=http://doi.wiley.com/10.1002/cssc.201402502|journal=ChemSusChem|language=en|volume=7|issue=10|pages=2939–2946|doi=10.1002/cssc.201402502|pmid=25138922|via=}}{{Dead link|date=January 2022 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> LiTFSI is toxic if swallowed. It is toxic in contact with skin and can cause severe skin burns. Therefore, sealed batteries must not be opened. ==References== {{reflist}} {{chemistry-stub}} [[Category:Lithium compounds]]
