· Na2 V4 O8

Na2V4O8 is a layered oxide semiconductor compound containing sodium and vanadium, belonging to the class of transition metal oxides with potential electrochemical activity. This material is primarily investigated in battery and energy storage research, particularly for sodium-ion battery cathodes and electrochemical capacitor applications, where its layered structure and mixed-valence vanadium chemistry offer advantages in ion intercalation and electron transport compared to conventional lithium-based systems. As a research-phase compound rather than a mature commercial material, Na2V4O8 represents the broader family of vanadium oxide frameworks being explored to reduce reliance on lithium resources and enable more sustainable, cost-effective energy storage solutions.
