· Na2 V2 Si2 O8

Na₂V₂Si₂O₈ is a vanadium-silicon oxide ceramic compound that belongs to the class of mixed-metal oxide semiconductors. This material is primarily investigated in research contexts for electrochemical energy storage and ion-conduction applications, particularly as a potential cathode or electrolyte component in sodium-ion battery systems. Its layered silicate structure and vanadium oxidation states make it notable for ion-transport behavior, positioning it as a candidate material for next-generation battery chemistries where sodium-based systems offer cost and sustainability advantages over lithium alternatives.
