PARASITIC REACTIONS AND THE BALANCE OF MATERIALS IN LITHIUM BATTERIESFOR IMPLANTABLE MEDICAL DEVICES

The parasitic reactions that occur in lithium/silver vanadium oxide ce lls have been investigated by microcalorimetry. Reactions between lith ium and components of the electrolyte are the biggest contributors to beat output. The rate of parasitic reaction of lithium needs to be kno wn to ensure that the batteries are not anode-limited. This parameter is one of many included in a calculation of the balance of materials i n the cell. This calculation ensures the proper balance of electrodes and electrolyte solution in a constrained volume and also determines e lectrode dimensions.
