The Mechanism of Fluorine Doping for the Enhanced Lithium Storage Behavior in Cation-disordered Cathode Oxide

Scientific Achievement

We identify the fluoridation in disordered rock-salt materials benefits a more interconnected lithium diffusion network for achieving high-capacity DRX cathodes.

Significance and Impact

We anticipate that future research focusing on the multiscale structural design of DRX materials will unlock new possibilities for further performance advancements, such as optimizing the connectivity of the lithium percolation network and tailoring the composited SRO.

Research Details

  • Neutron total scattering data were modeled with the reverse Monte Carlo approach.
  • Detailed battery performance studies and link it to the local structural aspects.
