Three dimensional-transition element selectivity for electrochemical hydrogen charging in MgAlNi-based lightweight high-entropy alloys as electrodes for M-MH batteries

Journal of Magnesium and Alloys
This study reports the effect of 3d transition elements on the electrochemical hydrogen storage of MgNiAl-based high-entropy alloys (HEAs). The HEAs were designed using empirical equations that relate thermodynamic parameters such as enthalpy and valence

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 ...

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

Advanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

MXene‐Based Electrocatalysts for Sustainable Nitrogen Conversion: From Ammonia Oxidation to Nitrogen and Nitrate Reduction

Advanced Materials Interfaces, EarlyView.
This review compares MXene‐based electrocatalysis for ammonia oxidation, nitrogen reduction, and nitrate reduction, highlighting reaction‐dependent differences in catalytic performance and stability. MXenes are generally more compatible with cathodic nitrogen and nitrate reduction, whereas anodic ammonia oxidation raises stability concerns.
