Ferrous Pyrophosphate Hollow Nanorods Enable Lithium Metal Batteries Under Low Negative/Positive Capacity Ratios

Advanced Materials, EarlyView.
N‐doped carbon‐coated ferrous pyrophosphate (Fe2P2O7@NC) hollow nanorods are rationally synthesized through a self‐template method. The Fe2P2O7@NC hollow nanorods facilitate uniform Li deposition as a Li host by generating LiF on the electrode/electrolyte interface, and form Li2O in the bulk phase of the electrode.

Key plasma processes in LaB6 thermionic hollow cathodes operating in He, D2, Ar, and Xe at 4–200 Pa and 0.25–5 A cm−2

AIP Advances
Key physical processes in a thermionic hollow cathode plasma are identified using an experimental dataset and a zero-dimensional model. Model predictions for voltage are in generally good agreement with the dataset when it is assumed that the plasma is ...

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Design of High‐Energy Anode for All‐Solid‐State Lithium Batteries–A Model with Borohydride‐Based Electrolytes

Advanced Materials Interfaces, EarlyView.
This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
