CARBON FIBER, METHOD FOR PRODUCING THE SAME AND ELECTRODE FOR CELL |
摘要 |
Fine carbon fibers having a fiber diameter of 1 mu m or less, an interlayer distance d002 between carbon layers as determined by an X-ray diffraction method of 0.335 to 0.342 nm or less and satisfying d002 < 0.3448 - 0.0028 (log phi ) where phi stands for the diameter of the carbon fibers, and a thickness Lc of the crystal in the C axis direction of 40 nm or less. Fine carbon fibers containing boron in crystals of the fiber. The fine carbon fibers can be produced by using vapor-grown fine carbon fibers as a raw material, adding a boron or a boron compound to the material; pressing the mixture to regulate the bulk density to preferably 0.05 g/cm<3> or more; and heating at a temperature of 2000 DEG C or higher. <IMAGE> |
