Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, EarlyView.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.

Self‐Assembled Lipids as Soft Dielectrics

Advanced Functional Materials, EarlyView.
Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.
