NOVELTY - A vapor-grown graphite fibers (VGGF) composition, comprises: a carbon ingredient containing a carbon content of greater than or equal to 99.9 wt.%, where the carbon ingredient has a graphitization degree of greater than or equal to 75%, and comprises fibrous VGGP comprising graphite fibers having a three-dimensional (3-D) linkage structure, where the content of the graphite fibers having the 3-D linkage structure in the fibrous VGGF measured by a scanning electron microscopy (SEM) is 5-50 area%; and non-fibrous carbon, where an area ratio of the non-fibrous carbon to the fibrous VGGF measured by the SEM is less than or equal to 5%.    USE - As vapor-grown graphite fibers (VGGF) composition, useful to form mixture containing N-methyl-2-pyrrolidone, or resin or inorganic member (all claimed). The VGGF composition is useful in electronic devices, lithium ion battery electrode material, fuel cell material, electrically-conductive composite material, thermally-conductive composite material, and composite material having mechanical strength.    ADVANTAGE - The VGGF composition provides improved VGGF composition than conventional VGGF compositions. The conventional VGGF have disadvantages that it contains too much non-fibrous carbon, thus decreases number of continuous networks to be constructed in composite material to affect performance of composite material. Further, since not being highly graphitized, conventional VGGF fails to promote thermal and electrical conductivity performances of composite material. Also, metal catalyst used in the production of conventional VGGF has not been removed to be within proper range, which has caused detrimental effect on electrochemical reaction to be applied in field of energy e.g. has limited efficacy in promoting power and cycle life of battery. The improved VGGF composition soles problems of conventional VGGF which are not highly graphitized and contain too much non-fibrous carbon and metal content (impurities). The VGGF composition has high fiber purity. The VGGF composition is highly graphitized product including carbon ingredient containing carbon content of greater than or equal to 99.9 wt.%, carbon ingredient has graphitization degree of greater than or equal to 75% (preferably greater than or equal to 85%), and area ratio of non-fibrous carbon to fibrous VGGF measured by scanning electron microscopy (SEM) of less than or equal to 5%. The VGGF composition has metal content of less than 200 ppm, and water content of less than 0.2 wt.%. The VGGF composition has good thermal and electrical conductivities, and high strength. A pasty material formed by uniformly mixing N-methyl-2-pyrrolidone (NMP) with 30 wt.% of VGGF composition has volume resistance of smaller than 500-cm, and good oxidation resistance. Thus applications of VGGF composition and mixtures including VGGF composition may greatly increase number of networks constructed by VGGF composition in composite material, minimize detrimental effect of impurities (non-fibrous carbon, water content and metal content), and greatly improve performance of composite material including electrical and thermal conductivities and strength. The VGGF can be better applied on material, and material with addition of VGGF has better efficacy for applications in electronic devices, thus meeting the advanced industrial requirements. When VGGF composition is tested by thermogravimetric analyzer (TGA) for analysis under test conditions including temperature increasing rate of 10 degrees C/minute and air flow rate of 10-20 ml/minute, thermal decomposition onset temperature of VGGF composition is found to be greater than 700 degrees C. Hence, VGGF composition is suitable for used in energy materials, such as, additive for lithium ion battery electrode material, or composite material with high thermal and electrical conductivities and high strength, thus meeting advanced industrial requirements.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a mixture, comprising: 30 wt.% of the VGGF composition; and N-methyl-2-pyrrolidone (NMP), where the mixture has a volume resistance of smaller than 50 Omega .cm; and    (2) a mixture, comprising: a resin or an inorganic member; and the VGGF composition.
