Thermal Expansion of Electrofused MgO-Based Spinel Systems Containing Fe₂O₃, Al₂O₃-Fe₂O₃, Al₂O₃-Cr₂O₃-Fe₂O₃ and Al₂O₃-NiO-Fe₂O₃

Crystals
Magnesia-spinel multicomponent materials have been used as refractories for a long time. In addition to a few binary systems, the influence of spinel phases on the thermal expansion (α) of MgO or the resulting compound has not been studied so far.

Investigation of Moisture‐Induced Degradation Mechanisms and a Reviving Strategy for Sulfide‐Based Solid Electrolytes in All‐Solid‐State Composite Cathode

Advanced Energy Materials, EarlyView.
Moisture exposure induces the formation of reductive solid phases on argyrodite Li6PS5Cl, which destabilize Ni‐rich cathodes by extracting lattice oxygen and inducing surface reconstruction. A brief oxygen‐assisted annealing treatment quenches these reductive phases, restores interfacial stability, and enables effective regeneration and reuse of ...
