Abstract

New cathode materials will lead to technological advances for implantable cardioverter defibrillators, ICDs, such as reduced size and increased performance of the device. While the industry standard silver vanadium oxide Ag 2V 4On 11 exhibits great chemical/ electrochemical stability, dense silver oxide fluoride materials are advantageous because of high crystal density that can result in an increased capacity above 3 V. This report highlights the reactivity at room temperature between Ag 2O and V 2O 5 in an aqueous HF solution which affords a rapid precipitation of sub-micrometer sized Ag 4V 2O 6F 2 (SVOF), a high capacity Li-battery cathode material. This system opens new and novel synthetic strategies in the design of new oxide fluoride materials.
