Ca1 V4 O8

Ca₁V₄O₈ is a mixed-valence calcium vanadium oxide ceramic compound belonging to the family of vanadium bronzes and layered oxide semiconductors. This material is primarily explored in research contexts for its potential electrochemical and electronic properties, particularly in energy storage and catalytic applications where vanadium oxides show promise as alternatives to conventional transition metal oxides. The compound's appeal lies in its mixed oxidation states and structural flexibility, which researchers investigate for battery electrodes, supercapacitors, and catalytic systems, though it remains largely in the developmental phase compared to more established vanadium oxide compositions like V₂O₅.
