Particle‐Size‐Dependent Lithium‐Ion Transport in PEO/LLZO Composite Electrolytes

open access: yesSmall Structures, Volume 7, Issue 6, June 2026.
A continuum modeling framework quantifies the critical polymer/ceramic interfacial resistance required for ceramic fillers to reduce polarization in PEO/LLZO composite electrolytes. The model shows that this threshold scales linearly with LLZO particle size, while remaining largely insensitive to ceramic loading.
