Mechanochemical Treatment for the Extraction of Lithium from Hard Rock Minerals: A Comprehensive Review

open access: yesMetals
Lithium (Li) extraction from Li hard rock minerals involves thermal activation at elevated temperatures and the use of corrosive reagents. The reagents can damage the environment if they are not adequately contained as part of the process, and the high ...

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

open access: yesAdvanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

Unveiling the High‐Voltage Reactivity and Gas Evolution With Aluminum‐Based Chloride and Oxychloride Catholytes in Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The work examines the electrochemical and interfacial behaviors of crystalline NaAlCl4 and amorphous Na–Al–oxychloride solid electrolytes with NaNi0.5Mn0.5O2 cathodes. Operando gas evolution and ToF‐SIMS analyses highlight that pure chloride solid electrolytes offer greater interfacial stability and safety compared to the oxychloride solid electrolytes

Electrolyte‐free cathode design for solid‐state batteries demonstrated with bifunctional Li2VCl4

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
The “electrolyte‐free” cathode design is demonstrated by utilizing the ion‐conducting active material Li2VCl4. This design is exclusively viable within all‐solid‐state battery configurations, where both active materials and electrolytes exist in the solid state.
