Patent ID: 7754111

Claim:
A method for providing a cathode active material, comprising the steps of: a) providing a silver-containing ingredient selected from the group consisting of Ag, Ag 2 O, Ag 2 CO 3 , AgNO 3 , AgNO 2 , Ag 2 O 2 , AgVO 3 , and Ag (CH 3 CO 2 ); b) providing a vanadium-containing compound selected from the group consisting of V 2 O 5 , NH 4 VO 3 , AgVO 3 , VO, VO 1.27 , VO 2 , V 2 O 4 , V 2 O 3 , V 3 O 5 , V 4 O 9 , and V 6 O 13 ; c) providing a fluorine-containing compound selected from the group consisting of AgF, VOF 3 , and mixtures thereof; d) mixing the silver-containing ingredient, the vanadium-containing compound and the fluorine-containing compound together; e) heating the mixture to obtain fluorinated silver vanadium oxide as a cathode active material; f) providing a solution of an organic solvent having the fluorinated silver vanadium oxide mixed therein thereby forming an admixture paste; g) subjecting the paste to at least one pressing step thereby forming a cathode sheet; h) removing any residual solvent material from the cathode sheet; i) subjecting the cathode sheet to a forming means that serves to provide at least one cathode plate having a desired geometric shapes; and j) laminating at least one of the thusly formed cathode plates on at least one side of a current collector.
