Abstract
The invention provides heat-treated silver vanadium oxide for use in the cathodes of electrochemical cells, particularly in implantable medical devices. The heat-treated silver vanadium oxide is capable of being pressed into a pellet having a pressed pellet density of about 3.10 g/cm.sup.3 to about 3.45 g/cm.sup.3 when about 2 grams of the heat-treated silver vanadium oxide are uniaxially pressed into a pellet using a 1.6 cm diameter cylindrical die with a 7500 pound force applied for 5 seconds.
