  • Usage of stronger Li+-coordinating nitriles such as acetonitrile and linear and cyclic ether cosolvents improved salt dissociation and solubility, resulting in a substantial increase at low temperature.

    “Usage of the stronger (compared to semifluorinated short alkanes) Li + coordinating nitriles such as acetonitrile, linear and cyclic ether cosolvents improved salt dissociation and solubility resulting in a substantial increase at LT.”

    From Review on Low-Temperature Electrolytes for Lithium-Ion and Lithium Metal Batteries (2023) · cites this paper as [76]

    Section 2.1 (page unavailable) reports that acetonitrile coordinates more strongly with Li⁺ than fluoromethane, that the salt dissolves in the acetonitrile-containing mixture, and that the electrolyte has high low-temperature conductivity. It does not report using linear or cyclic ether cosolvents or establish improved salt dissociation as the cause of that conductivity. (LLM, conf=0.87)

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.
