Electrochemical performances of spinel oxides as cathodes for intermediate temperature solid oxide fuel cells

, 2013
The spinel-type oxides of (Mn, Co, Cu)(3)O-4 prepared via a citric EDTA acid process were investigated as candidate cathodes of intermediate temperature solid oxide fuel cells (IT-SOFCs).

Sublattice‐Resolved Magnetoelastic Coupling and Opposing Pressure Responses in the Frustrated Magnetocaloric GdMn2O5

Advanced Science, EarlyView.
In GdMn2O5, sublattice‐resolved EXAFS and diffraction analysis reveal pronounced spin‐phonon coupling and an unexpected opposing pressure response: the Mn‐driven Néel temperature slightly decreases while the Gd‐sublattice ordering temperature rises under pressures up to 0.86 GPa.

Spinel web: an interactive web application for visualizing the chemical composition of spinel group minerals

, 2020
The spinel group minerals provide useful information regarding the geological environment in which the host rocks were formed, constituting excellent petrogenetic indicators, and guides in the search for mineral deposits of economic interest.

Water/Ionic Liquid Hybrid Electrolyte for High Cycling Stability and Low‐Temperature Adaptability in Aqueous Lithium‐Ion Battery

Advanced Science, EarlyView.
A dilute hybrid electrolyte containing only 10 mol% [EMIM][DEP] simultaneously reorganizes the water hydrogen‐bond network and creates an ionic‐liquid‐rich region at the anode. This coupled bulk and interfacial regulation suppresses freezing and hydrogen evolution, broadens the electrochemical stability window, and enables an aqueous LMO/LTP full cell ...

Anion‐Driven Surface Reconstruction Enables Direct Regeneration of LiCoO2 Cathode Material

Advanced Science, EarlyView.
The anion scpecies in molten salt systems critically govern the surface reconstruction of regenerated LiCoO2. LiOH−LiCl flux, featuring strong Cl− adsorption and facile dissociation, directs preferential relithiation on (003) facets and forms a Li−O enriched interface.
