Time-Temperature-Transformation Diagrams to Navigate the Nucleation and Quenchability of Metastable α-Li₃PS4

α-Li₃PS₄ is a promising solid-state electrolyte with the highest ionic conductivity among its polymorphs. However, its formation presents a thermodynamic paradox: the α-phase is the equilibrium phase at high temperature and transforms to the stable γ-Li3PS4 polymorph when cooled...

Potassium-Ion Conducting Amorphous-Based Chlorides KTaCl6 Prepared via Mechanochemistry

Abstract All-solid-state potassium batteries have attracted considerable attention as energy storage devices. The development of suitable ionic conductors has received significant attention for the commercialization of the batteries. Here, we report the potassium-ion conductors K...
