Fine‐Tunning BaCo0.4Fe0.4Zr0.1Y0.1O3−δ‐Based Air Electrodes for Reversible Protonic Ceramic Cells via Co‐Engineering A‐site Deficiency and Nickel Content

open access: yesAdvanced Functional Materials, EarlyView.
A synergistic strategy combining A‐site deficiency and B‐site nickel doping yielded a BCFZYN‐095‐01 nanocomposite air electrode for reversible protonic ceramic cells with superior ORR/OER activities. B‐site deficiency in the perovskite lattice enhances proton conduction, and nickel doping within the bulk facilitates oxygen transport.

Molecular‐Level Dual‐Ionophilic Passivation for High‐Areal‐Capacity Lithium Metal Anodes on Nanostructured Paper Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
The effect of a molecular‐level dual‐ionophilic chitosan passivation layer is investigated on a nanostructured paper electrode featuring an interconnected network structure of highly oxygen‐functionalized single‐walled carbon nanotubes (C‐NPE). This molecular coating enabled a high Coulombic efficiency (>99.0%) and stable cycling over 350 cycles at an ...

Heterostructured Sn:SnO2 Nanodots for High‐Performance Li–S Batteries with Kinetics‐Enhanced Cathode and Dendrite‐Free Anode

open access: yesAdvanced Functional Materials, EarlyView.
Heterostructured Sn:SnO2 nanodots decorated on reduced graphene oxide can simultaneously enhance conversion kinetics and inhibit dendrite growth, enabling stable lithium–sulfur batteries. Abstract The practical application of lithium–sulfur batteries is limited by polysulfide shuttling and sluggish reaction kinetics at the cathode, as well as ...

Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

open access: yesAdvanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...
