## Title

- title: Low-Dose Nanoscale Visualization of Crystal Phases in Epitaxial Cathodes
    via Cepstral Matching of Scanning Nanobeam Electron Diffraction
  title_type: original
  lang: en

## Description

- description: Layered cathodes are essential for achieving a high energy density
    in rechargeable lithium-ion batteries, but they suffer from capacity fade due
    to local crystal phase transitions during charge−discharge cycles. Understanding
    these phase transitions is essential to minimizing their effects, but their nanometer
    size and sensitivity to experimental conditions make observation difficult. Here,
    we visualized nanometer-scale crystal phases within an epitaxial LiCoO2 cathode
    after 100 charge−discharge cycles by matching experimental and simulated cepstra
    derived from scanning nanobeam electron diffraction. While the LiCoO2 bulk remained
    a layered structure, spinel- and rocksalt-type phases were observed within 3 nm
    of the cathode−electrolyte interface. The developed method achieved a spatial
    resolution of 1.5 nm across a field of view of several hundred nanometers with
    minimal electron beam damage. The cepstral matching analysis offers valuable insights
    into the interfacial phase transitions and will aid in the design of high-performance
    lithium-ion batteries.
