NOVELTY - Composition of matter comprises a styrene-butadiene rubber (SBR) polymer binder and polyvinylidene difluoride (PVDF) coated graphite particles.    USE - The composition of matter is useful in an electrode e.g. anode and cathode, of a battery (all claimed), preferably lithium ion battery.    ADVANTAGE - The electrode uses low amount of the PVDF binder to reduce the cost of the PVDF materials. The composition of matter prevents lithium-ion blocking effect exerted by a SBR coating on active material surface in the SBR polymer binder, and fully or partially replaces the PVDF with the SBR binder in the electrode and retains and/or improves the performance characteristics including rate, cycle, and storage life of the SBR binder electrode.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) an electrode comprising the composition of matter;    (2) a battery comprising a cathode, a separator, an anode comprising the SBR polymer binder and the PVDF coated graphite particles, and an electrolyte;    (3) preparing the PVDF coated graphite particles comprising dissolving PVDF in N-methylpyrrolidone (NMP) solvent to form a PVDF/NMP solution, adding graphite particles to the solution, and evaporating NMP solvent;    (4) preparing the composition of matter comprising providing the PVDF coated graphite particles and mixing the PVDF coated graphite particles in a SBR polymer binder solution, and evaporating the solution;    (5) a method for forming an electrode comprising providing the PVDF coated graphite particles and mixing the PVDF coated graphite particles in the SBR polymer binder solution to form a slurry, coating the slurry on a current collector, and evaporating the slurry coated on the current collector, or providing polyethyleneoxide coated graphite particles, mixing the polyethyleneoxide coated graphite particles in the SBR polymer binder solution to form the slurry, coating the slurry on a current collector, and evaporating the slurry coated on the current collector; and    (6) a method for preparing polyethyleneoxide coated graphite particles comprising dissolving polyethyleneoxide in an ether solvent to form a solution, adding graphite particles to the solution, and evaporating the ether solvent.    DESCRIPTION OF DRAWING(S) - The figure shows schematic cross-sectional view of an electrode with the PVDF coated graphite particles and the SBR binder.
