Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In rationally designed LGEs, solvated FSI- and dimethyl ether dominate the solvation structure, which is believed to reduce the free Me2O solvent amount, leading to improved oxidative stability and salt decomposition to form a LiF-rich SEI on the anode.

    “In rationally designed LGEs, solvated FSI -and dimethyl ether (Me 2 O) dominate the solvation structure, which is believed to reduce the free Me 2 O solvent amount leading to the improvement of the oxidative stability and the salt decomposition to form a LiF-rich SEI on the anode.”
  • Meng's group developed a novel LGE by adding the simplest liquefied ether to a non-flammable low-solvating hydrofluorocarbon mixture.

    “Meng's group [78] recently developed a novel LGE by adding the simplest (liquefied) ether to a non-flammable lowsolvating hydrofluorocarbon mixture.”
  • The LGE with oxidation stability up to 4.4 V enabled Li/NMC622 cells to exhibit stable cycling properties from -60 to 55 °C.

    “The LGE with oxidation stability up to 4.4 V enabled Li/NMC622 cells exhibiting stable cycling properties from -60 to 55 °C.”
  • The LGE based on 1,1,1,2-tetrafluoroethane and pentafluoroethane delivered high ionic conductivity >3 mS cm-1 from -78 to 80 °C, with non-flammable and fire-extinguishing features.

    “The LGE based on 1,1,1,2-tetrafluoroethane and pentafluoroethane delivered high ionic conductivity > 3 mS cm -1 within the temperature range from -78 to 80 °C, with non-flammable and fireextinguishing features.”
  • Lithium cycling at >99% Coulombic efficiency for over 200 cycles at 3 mA cm-2 and 3 mAh cm-2 was demonstrated.

    “As a result of the beneficial solvation chemistry and a fluorine-rich environment, a lithium cycling at > 99% Coulombic efficiency for over 200 cycles at 3 mA cm -2 and 3 mAh cm -2 was demonstrated.”

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.
