The present invention comprises an electrode material comprising (a) a polymeric binder, (b) a lithium-based electrochemically active material, and (c) an electrically conductive filler; The polymeric binder comprising at least one sulfur-based functional group; Wherein the electrode material is characterized in that the binding energy between the at least one sulfur-based functional group and the lithium-based electrochemically active material is from about 0.3 eV to about 2.5 eV. The present invention also provides a method for manufacturing a lithium secondary battery, comprising the steps of: (i) mixing a lithium-based electrochemically active material, an electrically conductive filler and a polymer binder to form an electrode material; And (ii) contacting the electrode material with a current collector to form a battery electrode, wherein the polymer binder comprises at least one sulfur-based functional group. |
