Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • Lithium cobalt oxide (LiCoO2) is a key cathode material for batteries, also showing potential in electrocatalysis and electrochemical random access memory (ECRAM).
  • Understanding nanoscale phase transformations, strain, and diffusional anisotropy in LiCoO2 is crucial for optimizing its performance in various applications.

Purpose of the Study:

  • To investigate how phase transformations in LiCoO2 scale down to nanometer dimensions.
  • To explore the effects of strain and surface energy on the electrochemical properties of isolated LiCoO2 islands.

Main Methods:

  • Epitaxial growth of LiCoO2 islands using pulsed laser deposition.
  • Electrochemical cycling of individual islands.
  • Conductive atomic force microscopy (c-AFM) for phase imaging.
  • Photoemission electron microscopy (PEEM) for cross-validation and statistical analysis.

Main Results:

  • Above 20 nm thickness, LiCoO2 islands exhibit a kinetically arrested state with phase boundaries perpendicular to Li-planes.
  • Smaller islands (<20 nm) show a higher conductive fraction, suggesting surface energy dominance below a critical dimension and a striping pattern in 14 nm islands.
  • Applied strain significantly alters current flow, indicating its critical role in electrochemical performance at the nanoscale.

Conclusions:

  • Nanoscale morphology and strain critically influence the electrochemical behavior of LiCoO2.
  • Surface energy effects become dominant in thinner islands, altering their phase behavior.
  • The findings are essential for advancing battery technology, electrocatalysis, and ECRAM applications.
