Abstract

Lithium metal is an ideal battery anode. However, dendrite growth and limited Coulombic efficiency during cycling have prevented its practical application in rechargeable batteries. Herein, we report that the use of highly concentrated electrolytes composed of ether solvents and the lithium bis(fluorosulfonyl)imide salt enables the high-rate cycling of a lithium metal anode at high Coulombic efficiency (up to 99.1%) without dendrite growth. With 4 M lithium bis(fluorosulfonyl)imide in 1,2-dimethoxyethane as the electrolyte, a lithium|lithium cell can be cycled at 10 mA cm(-2) for more than 6,000 cycles, and a copper|lithium cell can be cycled at 4 mA cm(-2) for more than 1,000 cycles with an average Coulombic efficiency of 98.4%. These excellent performances can be attributed to the increased solvent coordination and increased availability of lithium ion concentration in the electrolyte. Further development of this electrolyte may enable practical applications for lithium metal anode in rechargeable batteries.

  • When electrolytes containing high concentrations of LiTFSI or LiFSI are used in Li metal anode cells, they can form salt anion-derived SEI with a LiF-rich component that is beneficial for anode protection and electrochemical performance.

    “When the electrolytes containing high concentration of these salts are used in Li metal anode cells, they can form salt anion-derived SEI with a LiF-rich component which is beneficial for anode protection and electrochemical performance [104].”

    From Review on Low-Temperature Electrolytes for Lithium-Ion and Lithium Metal Batteries (2023) · cites this paper as [104]

    The Results section (“Formation of a stable SEI layer”; page not available) reports that a protective SEI forms with 4 M LiFSI-DME and that increasing fluoride content during cycling may result from anion degradation. It does not identify the SEI as LiF-rich or establish the same SEI mechanism for highly concentrated LiTFSI in Li-metal cells; its discussion of concentrated LiTFSI concerns Li|graphite cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
