Electrochemically Induced Interphase by Complex Hydride Anions in Argyrodite Solid Electrolytes for Stable Lithium Metal All‐Solid‐State Batteries

Advanced Science, EarlyView.
Complex hydride anion substitution in argyrodite electrolytes has attracted attention for improving interfacial stability, yet the influence of these anions at Li metal interfaces remains unclear. This work shows that electrochemically formed BH4−‐derived interphases enable stable high‐current full‐cell cycling.

Al─N Co‐Doped LLZO Solid Electrolytes via One‐Step Sintering: Toward High Ionic Conductivity

Advanced Science, EarlyView.
Al–N co‐doped LLZO solid electrolytes were prepared via a one‐step sintering process, which not only simplifies fabrication process, but also diminishes Li loss during high‐temperature sintering in conventional fabrication process. The Al–N co‐doped LLZO achieves a high ionic conductivity of 2.19 × 10−3 S cm−1 because the co‐doping reduces the energy ...

Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, EarlyView.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...
