Abstract

Performances of lithium-ion batteries at subambient temperatures are extremely restricted by the resistive interphases originated from electrolyte decomposition, especially on the anode surface. This work reports a novel strategy that an anode interphase of low impedance is constructed by applying an electrolyte additive dimethyl sulfite (DMS). Electrochemical measurements indicate that the as-constructed interphase provides graphite/LiNi 0.5 Co 0.2 Mn 0.3 O 2 pouch cells with excellent low-temperature performance, outperforming the interphase constructed by 1,3,2-dioxathiolane 2,2-dioxide (DTD), a common commercially used electrolyte additive. Spectral characterizations in combination with theoretical calculations demonstrate that the improved performance is attributed to the unique molecular structure of DMS, which presents appropriate reduction activity and constructs the more stable and ionically conductive anode interphase due to the weaker combination of its reduction product with lithium ions than DTD. This rational design of interphases via an additive structure has been proven to be a low cost but rather an effective approach to tailor the performances of lithium-ion batteries.

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 DTD system had lower resistance than baseline at room temperature, but at low temperature its charge transfer resistance increased significantly and was higher than baseline, implying sluggish charge transfer of DTD-formed SEIs at low temperatures.

    “The DTD system also had lower resistance compared to baseline at RT, while the charge transfer resistance of the DTD system at LT increased significantly and was even higher than the baseline electrolyte, implying sluggish charge transfer of DTD formed SEIs at LTs.”
  • There are competing arguments in the literature that improved battery performance at low temperatures was obtained by decreasing inorganic species including LiF in SEIs.

    “there are competing arguments regarding the effects of inorganic components of SEIs in the literature claiming that improved battery performance was obtained at LTs by decreasing inorganic species including LiF in SEIs.”
  • The DMS reduction product CH3OSO has lower binding energy with Li+ than DTD (OCH2CH2SO3), suggesting faster ionic migration through such SEI.

    “DMS reduction products (CH 3 OSO) has lower binding energy with Li + compared that of DTD (OCH 2 CH 2 SO 3 ), suggesting a faster ionic migration through such SEI.”
  • Cells using DMS electrolytes delivered 74.28% of RT capacity at -20 °C and C/2, followed by DTD-based cells (68.64%) and electrolyte without additive (66.44%).

    “The cells using DMS electrolytes showed the best results (Fig. 15d), which delivered 74.28% of RT capacity, followed by the DTD-based cell (68.64%) and the electrolyte without additive (66.44%).”
  • The DMS-based electrolyte system had the lowest Rsei and Rct at both room and low temperatures, indicating more ionically conductive SEIs formed by DMS.

    “According to EIS results, the DMSbased electrolyte system had the lowest R sei and R ct at both RT and LT, indicating more ionic conductive SEIs formed by DMS.”

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.
