Silver Vanadium Oxide Fluoride, Ag₄V₂O₆F₂

Subcategory: Oxide, Other; Halide; Oxide

Key Words: SVOF, primary lithium battery cathode

Material Notes:
Silver Vanadium Oxide Fluoride, Ag₄V₂O₆F₂ (SVOF) is a being researched as a cathode for for high capacity lithium batteries. It has a higher accessible silver content and a higher capacity than the commercial cathode material Silver Vanadium Oxide (SVO; Ag₂V₄O₁₁). The SVOF cathode maintains a greater potential than SVO electrodes for extended periods of time, allowing optimal device performance essential for medical battery applications, such as implantable defibrillators. When used as a cathode in a lithium battery, SVOF has two distinct regions within the discharge curve - an upper plateau at 3.5 V attributed to silver reduction and a lower sloped region around 2.3 V attributed to the reduction of the vanadium oxide fluoride framework.
