Silver molybdate electrochemistry mimics cardiac defibrillator battery mechanism
Dr. Paul Smith
Arts and Sciences
In the implantable cardiac defibrillator battery, lithium ions and electrons displace silver ions from vanadium oxides as silver metal. Prior research has shown that the resulting atomically dispersed silver metal lowers the electrical resistance to sufficiently low values as to not require carbon additives in electrodes. This talk will discuss a systematic study of silver molybdate electrodes which mimic this mechanism in aqueous zinc electrolyte. Both powder x-ray diffraction and high angle annular dark field scanning transmission electron microscopy imaging were utilized to characterize electrodes before and after reduction. The trends which enable aqueous zinc ion batteries to perform well with predicted future materials that do not require carbon additives will be discussed.
