Thus, consideration of parasitic reactions that occur over long periods of time has elevated significance. One such life limiting reaction for several battery systems is the dissolution of the cathode material into the battery electrolyte.  This research investigates cathode solubility in the battery system used to power implantable cardioverter defibrillators (ICDs).  The benchmark lithium/silver vanadium oxide (Ag2V4O11, SVO) system used in these devices has an unpredictable long term stability limitation attributed to cathode material solubility, which results in deposits on the anode manifesting as increased battery resistance. In consideration of the thermal and chemical stability of phosphate based structures, solution formation of Ag2V4O11 was compared with the silver vanadium phosphorous oxide (AgwVxPyOz, SVPO) family of cathode materials, which exhibit electrochemical performance characteristics which are suitable for ICDs and other high rate applications. Solution formation data collected using inductively coupled plasma \u2013 optical emission spectroscopy (ICP-OES) was interpreted from a kinetic perspective to gain insight into the mechanisms by which the dissolution process took place. The lithium anodes from discharged electrochemical cells were investigated by several techniques including mapping by synchrotron based x-ray microfluorescence (XR\u00b5F) and oxidation state determination by microbeam x-ray absorption spectroscopy (\u00b5XAS).  These methods enabled visualization of the anode surface and solid electrolyte interphase (SEI) through mapping, and determination of oxidation state of deposited species on the recovered anodes. The results suggest that SVPO materials can reduce cathode solubility and anode passivation compared to SVO, making them promising alternative cathode materials for the ICD application."},{"label":"dcterms.available","value":"2017-09-20T16:51:56Z"},{"label":"dcterms.contributor","value":"Mayr, Andreas"},{"label":"dcterms.creator","value":"Bock, David Charles"},{"label":"dcterms.dateAccepted","value":"2017-09-20T16:51:56Z"},{"label":"dcterms.dateSubmitted","value":"2017-09-20T16:51:56Z"},{"label":"dcterms.description","value":"Department of Chemistry."},{"label":"dcterms.extent","value":"250 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/77092"},{"label":"dcterms.issued","value":"2015-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2017-09-20T16:51:56Z (GMT).
