CARBON-CARBON COMPOSITE PARTICLES, THEIR PREPARATION AND USE THEREFORE AS NEGATIVE ELECTRODE FOR LI-ION BATTERIES |
摘要 |
A composite of particles comprising a high crystallinity carbon and a low crystallinity carbon, wherein the low crystallinity carbon exhibits an average lattice constant d=(002) of 0.350 nm or more and a crystallite size L=(002) in the diffraction of C axis of 25 nm or less, as characterized by wide-angle X ray diffraction measurements, the high crystallinity carbon exhibits an average lattice constant d=(002) of 0.338 nm or less and a crystallinity size L=(002) in the diffraction of C axis of 40 nm or more, as characterized by wide-angle X-ray diffraction measurements, the high crystallinity carbon having at least 50% of its external surface embedded within or surrounded by a matrix of low crystallinity carbon. |
