Supercritical Fluid‐Based Synthesis of Nanomaterials for Energy Storage Applications: A Pathway Toward High‐Entropy Oxides

Battery Energy, Volume 5, Issue 6, November 2026.
Supercritical fluid (SCF) synthesis offers tunable solvent properties (T > Tc, P > Pc), enabling rapid nucleation, uniform composition, and controlled growth of nanomaterials. This approach facilitates homogeneous multication mixing and entropy stabilization, promoting single‐phase high‐entropy oxides (HEOs) for advanced electrochemical applications ...

Molten Salt‐Derived Double Transition Metal MXene (Ti2NbC2Tx) as a Capacitive Material for Energy Storage Applications

ChemElectroChem, Volume 13, Issue 20, 16 October 2026.
Molten‐salt synthesized Ti2NbC2Clx MXene was treated with APS to obtain O‐rich Ti2NbC2ClxOγ MXene. The replacement of chlorine termination with oxygen significantly enhances lithium‐storage behavior in LP30 electrolyte, leading to higher current response, and enhanced reversible Li+ intercalation compared with Cl‐terminated Ti2NbC2Clx MXene.
