Abstract

Frozen in time: The electrochemical processes occurring in a battery are highly dynamic. To understand the complexities of the charge and discharge cycles, you need to be able to watch the processes in situ or to freeze the battery rapidly for ex situ analysis. Li et al. applied cryo–electron microscopy techniques commonly used for studying biological samples to examine batteries. They identified the solid electrolyte interphase that forms, observed the interactions of Li with the interphase, and captured the formation of dendrites that can be detrimental to the lifetime of a battery. Science , this issue p. 506

  • LiF lattice signature was not detected in the FEC-derived SEI.

    “Strangely, the signature of Li fluoride (LiF) lattice was not detected, even though LiF is considered to be a primary reason for performance enhancement [162].”
  • The SEI formed in standard electrolyte resembles the mosaic structure predicted by Peled et al., which describes the SEI as a heterogeneous distribution of inorganic and organic components.

    “The SEI formed in this standard electrolyte resembles the mosaic structure predicted by Peled et al. [166], who described the SEI as a heterogeneous distribution of inorganic and organic components.”
  • The SEI formed in the presence of FEC is more ordered and appears to have a multilayer structure, consistent with the multilayer system proposed by Aurbach et al.

    “Instead of a random distribution of organic and inorganic components, the SEI formed in the presence of FEC is more ordered and appears to have a multilayer structure, consistent with the multilayer system proposed by Aurbach et al. [167].”
  • The crystalline grains in the SEI are inorganic components identified as Li oxide and Li carbonate by matching their lattice spacings.

    “These crystalline grains are the inorganic components of the SEI, identified to be Li oxide and Li carbonate by matching their lattice spacings.”
  • A completely different SEI structure is formed in carbonate-based electrolyte with 10% FEC.

    “They also observed a completely different SEI structure when it was formed in a carbonate-based electrolyte with 10% FEC.”

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.
