Rebalancing of lithium/silver vanadium oxide (LI/SVO) cells

摘要

The Li/SVO battery is comprised of an anode, a cathode, and an electrolyte in relative amounts where the battery is anode limited such that the battery discharge is completed as the open circuit battery voltage drops to about 2.6 volts. The battery has a Q-(anode)/Q+(cathode) of about 0.45-0.70 and a Velectrolyte/Q+(cathode) of about 1 cm3/Ah. The quantity of the electrolyte is provided only in the amount needed for the electrochemical reaction involving the cathode. An implantable cardiac defibrillator includes a capacitor capable of providing an intense shock for terminating a tachyarrhythmia in a patient and an anode limited Li/SVO battery which charges the capacitor upon detection of the tachyarrhythmia by providing a pulse of energy to the capacitor.
