Nonaqueous electrochemical cell having a mixed cathode and method of preparation

摘要

A cathode active material admixture comprising a metal, a metal oxide, a mixed metal oxide or a metal sulfide and fluorinated carbon, is described. A preferred admixture comprises copper-silver-vanadium oxide and CFx. Such a blended cathode active admixture is useful in a nonaqueous electrochemical cell discharged for extended periods under a light load interrupted by high rate pulse discharges, such as occurs in an implantable medical device.
