Beschreibung
Zusammenfassung:	A lithium/fluorinated carbon (Li/CFx) battery having a composite cathode including an electroactive cathode material, a non-electroactive additive, a conductive agent, and a binder. The electroactive cathode material is a single fluorinated carbon having a general formula of CFx, whereby x is an averaged value ranging from about 0.5 to about 1.2. The non-electroactive additive is at least one or a mixture of two or more oxides selected from the group comprising Mg, B, Al, Si, Cu, Zn, Y, Ti, Zr, Fe, Co, or Ni. The conductive agent is selected from the group comprising carbon, metals, and mixtures thereof. Finally, the binder is an amorphous polymer selected from the group comprising fluorinated polymers, ethylene-propylene-diene (EPDM) rubbers, styrene butadiene rubbers (SBR), poly (acrylonitrile-methyl methacrylate), carboxymethyl celluloses (CMC), and polyvinyl alcohol (PVA). Also, a method of reducing the initial voltage drop of a lithium/fluorinated carbon (Li/CFx) battery by providing a composite cathode which includes an electroactive cathode material having a general formula of CFx, whereby x is an averaged value ranging from about 0.5 to about 1.2, a non-electroactive additive, a conductive agent, and a binder.
