Cathode material for nonaqueous electrochemical cells |
摘要 |
A new cathode material for use in a high energy density electrochemical cell, preferably comprising silver and vanadium, is described. The new cathode material has the general formula AgxV2Oy and can comprise a beta -phase silver vanadium oxide having in the general formula x = 0.35 and y = 5.18 and a gamma -phase silver vanadium oxide having in the general formula x = 0.74 and y = 5.37 or a mixture of the phases. This new cathode material exhibits reduced voltage delay during high rate applications, such as when the cathode mixture is incorporated into a primary lithium electrochemical cell powering an implantable cardiac defibrillator. <IMAGE> |
