Na2 V4 O10

Sodium vanadium oxide (Na2V4O10) is an inorganic ceramic compound belonging to the mixed-valence vanadium oxide family, characterized by a layered crystal structure containing both V(IV) and V(V) oxidation states. This material is primarily investigated in electrochemical energy storage research, particularly as a cathode material or electrolyte component in sodium-ion batteries and vanadium redox flow batteries, where its ion-conduction properties and structural stability during charge-discharge cycling are valued. Compared to lithium-based systems, sodium vanadium oxides offer potential cost advantages and abundance benefits, though this compound remains largely in development phase rather than high-volume industrial production.
