NOVELTY - The exfoliated graphite-based hybrid composition for use as an electrochemical cell electrode of a lithium secondary battery, comprises micron- or nanometer-scaled particles or coating, which are capable of absorbing and desorbing alkali or alkaline metal ions comprising lithium ions, exfoliated graphite flakes that are substantially interconnected to form a porous, conductive graphite network comprising pores, and an amorphous carbon, polymeric carbon, carbon black, coal tar pitch, petroleum pitch or meso-phase pitch in physical contact with the particles or coating.    USE - The exfoliated graphite-based hybrid composition is useful as an electrochemical cell electrode of a lithium secondary battery (claimed), which is useful for high power density applications such as electric cars.    ADVANTAGE - The exfoliated graphite-based hybrid composition is capable of absorbing and desorbing lithium ions, and provides high cycle life, high reversible capacity and low irreversible capacity to the lithium secondary battery.    DETAILED DESCRIPTION - The exfoliated graphite-based hybrid composition for use as an electrochemical cell electrode of a lithium secondary battery, comprises micron- or nanometer-scaled particles or coating, which are capable of absorbing and desorbing alkali or alkaline metal ions comprising lithium ions, exfoliated graphite flakes that are substantially interconnected to form a porous, conductive graphite network comprising pores, and an amorphous carbon, polymeric carbon, carbon black, coal tar pitch, petroleum pitch or meso-phase pitch in physical contact with the particles or coating. The particles or coating reside in a pore of the network or are attached to a flake of the network. An amount of the exfoliated graphite is 5-90 wt.%, and an amount of particles or coating is 95-10 wt.%. The exfoliated graphite flakes are obtained from intercalation and exfoliation of a laminar graphite material consisting of natural graphite, synthetic graphite, highly oriented pyrolytic graphite, graphite fiber, carbon fiber, carbon nano-fiber, graphitic nano-fiber, spherical graphite or graphite globule, mesophase micro-bead, meso-phase pitch, graphitic coke and/or graphitized polymeric carbon. The graphite flakes have a specific surface area of greater than 500 m2/gm or an average thickness thinner than 2 nm. The particles have a dimension of less than 5 mu m or the coating has a thickness of less than 5 mu m. The particles or coating are substantially amorphous or comprise nano crystallites. The amorphous carbon phase is obtained from chemical vapor deposition, chemical vapor infiltration, or pyrolyzation of an organic precursor. An INDEPENDENT CLAIM is included for a lithium secondary battery.    DESCRIPTION OF DRAWING(S) - The diagram shows a cylinder-shape lithium ion battery.
