| titleOfInvention | Method to reduce resistance of lithium/silver vanadium oxide electrochemical cells |
| abstract | Increased Rdc in electrochemical cells is detrimental because under high rate discharge regimes, such as used in powering an implantable cardiac defibrillator (ICD), the amount of energy delivered by the cell over a given period of time is lower as Rdc increases. This reduction in delivered energy results in a longer period of time needed to fully charge the ICD capacitors so that it takes longer to deliver the necessary therapy. Further, an industry recognized standard is to pulse discharge cell about every 90 days to charge the capacitors in the ICD to or near their maximum energy breakdown voltage to heal microfractures that can occur in the capacitor dielectric oxide. However, the present invention requires initiation of more frequent current pulsing upon the detection of an increase in Rdc or charge time. This is even though the Rdc measurement may be below some threshold reading. More frequent pulsing is beneficial for reducing irreversible Rdc growth in the cell, which typically occurs in middle-of-life from about 25% to 70% depth-of-discharge. |
