▎ 摘　　要

NOVELTY - The fiber has a hollow space extending along its center axis. The fiber has an end surface with a portion of discontinuity in which ends of graphene sheets (4,6,8,10) are not bonded to one another. A portion of continuity (2a, 2b) comprising the graphene sheets in which one graphene sheet is bonded adjacent to another graphene sheet. The portion of continuity has a bent portion formed of three groups. USE - Used for a lithium battery, lead storage battery, a polymer battery, and a dry battery. ADVANTAGE - The fiber when mixed with matrix formed of rein or a similar material, exhibits excellent dispersibility, adhesion, deterioration resistance, electrical conductivity, and thermal conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (a) a method of producing graphitized fine carbon fiber (b) a gas conclusion material comprising a graphitized fine carbon fiber. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the structure of a graphitized fin carbon fiber. Portion of continuity (2a, 2b) Graphene sheets (4,6,8,10)
