9. A cell including an anode and a cathode wherein the cathode is prepared by a method of comprising the steps of mixing polymeric material selected from the group consisting of P2VP, P4VP and mixtures thereof with a quantity of iodine, and heating the mixture in a container, the heating step being further characterized by a treatment sequence selected from the group consisting of:
-
A. sealing the mixture in the container under vacuum and heating the mixture for a time at a temperature of at least about 150°
C.,B. sealing the mixture in the container with an inert atmosphere and heating the mixture for a time at a temperature of at least about 150°
C., andC. sealing the mixture in the container with an atmosphere selected from the group consisting of ambient, inert, and vacuum, heating the mixture for a time at a temperature of at least about 150°
C., and subjecting the mixture to a vacuum for a time following the heating step to remove volatiles. - View Dependent Claims (10, 11, 12)
