XSXiaotang ShiANAndrew J. NaylorTFTill Fuchs

Key Points

  • The study aims to investigate the mechanical properties of cathode–electrolyte interphase layers in high-voltage lithium-ion batteries.
  • Utilized scanning force microscopy for quantitative mechanical mapping.
  • Analyzed the cathode–electrolyte interphase on LiNi 0.5 Mn 1.5 O 4 electrodes.
  • Assessed changes during extended cycling.
  • The interphase mechanically homogenized during cycling.
  • An organic-dominated network formed in the interphase.
  • Indicates potential improvements in battery performance.

Abstract

Quantitative mechanical mapping via scanning force microscopy reveals that the cathode–electrolyte interphase on high-voltage LiNi 0.5 Mn 1.5 O 4 (LNMO) electrodes mechanically homogenized during extended cycling, forming an organic-dominated network.
