Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • The gel polymer cell containing 1 M LiPF6 in EC:DEC:DMC:EMC (1:1:1:3, volume ratio) delivered nearly full (>99%) room-temperature capacity when discharged at -40 °C using a C/10 rate.

    “The gel polymer cell containing electrolyte of 1 M LiPF 6 in EC:DEC:DMC:EMC (1:1:1:3, volume ratio) delivered nearly full (> 99%) RT capacity when discharged at -40 °C using a C/10 rate (Fig. 10a).”
  • After increasing the discharge rate to C/5, the gel polymer cell still delivered over 94% of room-temperature capacity.

    “After increasing the discharge rate to C/5, this cell still delivered over 94% of RT capacity.”
  • The ionic conductivity of polymer electrolytes is largely affected by the liquid electrolyte components.

    “This work suggested that the ionic conductivity of polymer electrolytes is largely affected by the liquid electrolyte components.”
  • The cell using MB-based electrolytes delivered 80% of its room-temperature capacity when discharged at -60 °C.

    “The cell using MB-based electrolytes delivered 80% of its RT capacity when discharged at -60 °C (Fig. 10b).”

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.
