 The bis(fluorosulfonyl)imide anion N(SO2F)2- (i.e., FSI-) (also referred to as bis(fluorosulfonyl)amide (i.e., FSA-) and imidodi(sulphuryl fluoride)) has attracted tremendous interest in recent years for its utility in both lithium salts and ionic liquids for battery electrolyte applications. To facilitate the understanding of the characteristics of this anion, crystal structures are reported here for the uncoordinated anion in LiFSI-based solvates with cryptand CRYPT-222 and tetraglyme (G4). These crystalline solvates were analyzed by Raman spectroscopy to aid in assigning the Raman bands to the modes of ion coordination found in liquid electrolytes. These structures, as well as a thorough review of other relevant crystallographic data, provide insights into the rather remarkable properties of the FSI- anion with regard to solvate formation and electrolyte properties.}, number={11}, journal={JOURNAL OF THE ELECTROCHEMICAL SOCIETY}, author={Han, Sang-Don and Sommer, Roger D. and Boyle, Paul D. and Zhou, Zhi-Bin and Young, Victor G. and Borodin, Oleg and Henderson, Wesley A.}, year={2022}, month={Nov} }

 Raman spectroscopy is widely used to evaluate the ionic interactions and solvates present in electrolytes. As shown here, however, Raman spectra for crystalline solvates containing the lithium bis(trifluoromethanesulfonyl)imide (or amide) (i.e., LiN(SO2CF3)2, LiTFSI, LiTFSA, LiNTf2 or LiTf2N) salt indicate that the commonly used vibrational band analyses are likely to be inaccurate and thus result in misleading conclusions about the ion interactions in liquid electrolytes with this salt. In particular, it is found by examining the Raman spectrum of a known crystalline solvate with the CIP-I-C2 coordination mode (i.e., a TFSI- anion with a C2 conformation coordinated to a single Li+ cation via a single oxygen atoms), that the vibrational band for this mode of coordination overlaps (or is closely positioned beside) that for the uncoordinated (i.e., SSIP) TFSI- anion. This realization further complicates the assessment of Raman data for LiTFSI-based electrolytes.}, number={6}, journal={JOURNAL OF THE ELECTROCHEMICAL SOCIETY}, author={Henderson, Wesley A. and Helm, Monte L. and Seo, Daniel M. and Trulove, Paul C. and De Long, Hugh C. and Borodin, Oleg}, year={2022}, month={Jun} }

The phase behavior of ethylene carbonate (EC)–LiTFSI mixtures indicates that two crystalline solvates form—(EC)3:LiTFSI and (EC)1:LiTFSI. Crystal structures for these were determined to obtain insight into the ion and solvent coordination. Between these compositions, however, a crystallinity gap exists. A Raman spectroscopic analysis of the EC solvent bands for the 3–1 and 2–1 EC–LiTFSI liquid electrolytes indicates that ∼86 and 95%, respectively, of the solvent is coordinated to the Li+ cations. This extensive coordination results in significantly improved anodic oxidation and thermal stabilities as compared with more dilute (i.e., 1 M) electrolytes. Further, while dilute EC–LiTFSI electrolytes extensively corrode the Al current collector at high potential, the concentrated electrolytes do not. A new mechanism for electrolyte corrosion of Al in Li-ion batteries is proposed to explain this. Although the ionic conductivity of concentrated EC–LiTFSI electrolytes is somewhat low relative to the current state-of-the-art electrolyte formulations used in commercial Li-ion batteries, using an EC–diethyl carbonate (DEC) mixed solvent instead of pure EC markedly improves the conductivity.}, number={1}, journal={ENERGY & ENVIRONMENTAL SCIENCE}, author={McOwen, Dennis W. and Seo, Daniel M. and Borodin, Oleg and Vatamanu, Jenet and Boyle, Paul D. and Henderson, Wesley A.}, year={2014}, month={Jan}, pages={416–426} }

The variation of the alkyl chains lengths on the cations plays a significant role in determining both the phase behavior and the physicochemical properties of the mixtures. Notably, the “tunability” of the properties of the IL mixtures is much easier to control than is found by simply making small structural changes to the ions in a given salt.}, number={8}, journal={JOURNAL OF PHYSICAL CHEMISTRY C}, author={Fox, Eric T. and Weaver, Joshua E.

LiDFOB was synthesized as previously described in the literature via direct reaction of boron trifluoride diethyl etherate with lithium oxalate. The crystal structure of the salt was determined from single crystal X-ray diffraction yielding a highly symmetric orthorhombic structure (Cmcm, a = 6.2623(8) Å, b = 11.4366(14) Å, c = 6.3002(7) Å, V = 451.22(9) Å3, Z = 4 at 110 K). Single crystal X-ray diffraction of a dihydrate of LiDFOB yielded a monoclinic structure (P21/c, a = 9.5580(3) Å, b = 12.7162(4) Å, c = 5.4387(2) Å, V = 634.63(4) Å3, Z = 4 at 110 K). Along with the crystal structures, additional structural information and the properties of LiDFOB (via 11B and 19F NMR, DSC, TGA and Raman spectroscopy) have been compared with those of LiBF4 and LiBOB to better understand the differences between these lithium battery electrolyte salts.}, number={22}, journal={JOURNAL OF POWER SOURCES}, author={Allen, Joshua L. and Han, Sang-Don and Boyle, Paul D. and Henderson, Wesley A.}, year={2011}, month={Nov}, pages={9737–9742} }

The melting point of the IL decreases with the addition of LiFSI and concentrated samples remain totally amorphous.
