Non-aqueous cell having a mixture of fluorinated carbon cathode materials

Abstract

The present disclosure relates generally to a cathode material suitable for use in a non-aqueous electrochemical cell that comprises a mixture of fluorinated carbon materials, and more particularly such a cell that comprises a mixture of three fluorinated carbon materials that each have distinct (from each other) discharge profiles (e.g., distinct voltages and capacities). The present disclosure additionally relates to a non-aqueous electrochemical cell comprising such cathode material and, in particular, to such a non-aqueous electrochemical cell that is lithium-based (i.e., a lithium, or lithium ion, non-aqueous electrochemical cell).
