Silver vanadium oxide preparation process

摘要

The invention provides a silver vanadium oxide composition for use in an electrochemical cell, the composition comprising heat-treated silver vanadium oxide prepared by a process comprising heat-treating as-synthesised silver vanadium oxide. The heat-treated silver vanadium oxide of the invention is capable of being pressed into a pellet having a pressed pellet density of about 3.10 g/cm<3> to about 3.45 g/cm<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 3,400 kg (7,500 pound) force applied for 5 seconds. The heat-treated silver vanadium oxide in accordance with the invention may be used in the cathodes of electrochemical cells, particularly in implantable medical devices.
