Elaboration and characterizations of glasses/glass-ceramics in the Na 2 O-V 2 O 5 -TeO 2 system for energy storage applications Open
Glasses and corresponding glass-ceramics were studied in the Na2O-V2O5-TeO2 (NVT) system. The thermal and electrical properties as well as the structure of parent glasses were determined by differential scanning calorimetry (DSC), electroc…

Structure, bonding and ionic mobility in Na-V-P-O glasses for energy storage applications through experiments, first-principles and machine learning-accelerated molecular dynamics Open
Na-V-P-O glasses are promising cathode materials for sodium ion batteries, and yet a thorough understanding of their atomic scale behavior has so far been elusive. In this work we integrate structural and electrochemical experiments with f…

Structure, bonding and ionic mobility in Na–V–P–O glasses for energy storage applications Open
A combined experimental and computational study by FPMD and MLIP-driven MD reveals structure, bonding, and Na-ion mobility in Na–V–P–O glasses, with heterogeneous Na transport and complex V coordination relevant to sodium-ion battery catho…

Atomic scale structure and dynamical properties of (TeO<sub>2</sub>)<sub>1−<i>x</i></sub>–(Na<sub>2</sub>O)<sub><i>x</i></sub> glasses through first-principles modeling and XRD measurements Open
We resort to first-principles molecular dynamics, in synergy with experiments, to study structural evolution and Na + cation diffusion inside (TeO 2 ) 1− x –(Na 2 O) x ( x = 0.10–0.40) glasses.
