Abstract

Carbonaceous anode materials in lithium‐ion rechargeable cells exhibit irreversible capacity, mainly due to reaction of lithium during the formation of passive surface films. The stability and kinetics of lithium intercalation into the carbon anodes are determined by these films. The nature, thickness, and morphology of these films are in turn affected by the electrolyte components, primarily the solvent constituents. In this work, the films formed on graphite anodes in low‐temperature electrolytes, i.e., solutions with different mixtures of alkyl carbonates and low‐viscosity solvent additives, are examined using electrochemical impedance spectroscopy (EIS) and solid‐state nuclear magnetic resonance techniques. In addition, other ex situ studies such as X‐ray diffraction, transmission electron microscopy, and electron energy loss spectroscopy were carried out on the graphite anodes to understand their microstructures. © 1999 The Electrochemical Society.

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?

  • Esters with shorter alkyl chains have the advantage of better ionic conductivity for the bulk electrolyte but the disadvantage of forming more resistive and less protective solid electrolyte interphases compared with longer-chain counterparts.

    “It was concluded that esters with shorter alkyl chains have the advantage in getting better ionic conductivity for the bulk electrolyte, but the disadvantage in forming more resistive and less protective SEIs as compared to longer chain counterparts.”

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.
