CARBON FIBER AGGREGATE AND METHOD FOR MANUFACTURING SAME, ELECTRODE MIXTURE LAYER FOR NON-AQUEOUS-ELECTROLYTE SECONDARY CELL, ELECTRODE FOR NON-AQUEOUS-ELECTROLYTE SECONDARY CELL, AND NON-AQUEOUS-ELECTROLYTE SECONDARY CELL

摘要

The present invention provides a carbon fiber aggregate that is characterized by comprising carbon fibers in which crystallite interplanar spacing (d002) measured using X-ray diffraction is 0.3400 nm or more, the average liber diameter being 10-900 nm, and the powder volume resistivity being 4.00×10⁻² Ω·cm or less when the packing density is 0.8 g/cm³.
