COPPER DOPED SVO COMPOUNDS AS HIGH RATE CATHODE MATERIALS

摘要

The present invention related to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from a combination of vanadium oxide and either a copper or a silver oxide and the other of a copper or a silver nitrate. The cathode material of the present invention provides an increased gravimetric energy density over the cathode active materials of the prior art along with an increased pulse voltage delivery capacity. This makes the cathode material of the present invention particularly useful for implantable medical applications.

主权项

1. An electrochemical cell, comprising:
a) an anode of a Group IA metal which is electrochemically, oxidizable to form metal ions in the cell upon discharge to generate an electron flow in an external electrical circuit connected to the cell; b) a cathode of electrically conductive material, wherein the cathode comprises a metal oxide matrix material comprising vanadium oxide and a mixture of either a copper oxide and a silver nitrate or a copper nitrate and a silver oxide; and c) an ionically conductive electrolyte solution activating the anode and the cathode.
