PRIONE

BEST VALUE INNOVATION

Technology
TMI Transition Metal Impurities

A technology that minimizes transition metal catalyst impurities such as Fe, Ni, and Co that can arise during CNT manufacturing, delivering high-purity materials.

  • World's FirstPurification-free Process
  • World's FirstZero Catalyst Impurities (0 ppm)
  • Low-temperature Process (under 600°C)
  • Low-cost Eco-friendly Process

World's First

Purification-free Process

  • The PRIONE process uses no transition metal catalysts
    such as Fe, Co, Ni, or Mo

  • Intellectual property for catalyst purification
    is no longer required

  • Because it is a purification-free process,
    no high-temperature reactor using halogen gas
    for catalyst purification is required

  • High-concentration acid treatment is also not needed,
    so no environmental cost is incurred

  • Since no purification is performed,
    no chemical or structural damage
    occurs to the synthesized CNTs

World's First

Zero Catalyst Impurities (0 ppm)

  • Because no transition metal catalyst is used,
    the impurity content from catalysts is 0 ppm

  • 0 ppm

    PRIONE's special catalyst can be removed
    to 0 ppm during the process

  • When used as a conductive additive for batteries,
    the more of PRIONE's special catalyst that remains as residue,
    the more it contributes to improved battery performance

Under 600°C

Low-temperature Process

  • The advantage of a low-temperature process is
    low cost driven by low power consumption

  • The temperature gradient in the reaction zone is small,
    enabling production of uniform quality

  • When doping hetero atoms such as nitrogen,
    the low-temperature process allows the doping amount to be greatly increased over a high-temperature process,
    enabling the manufacture of high-functionality CNTs

Low-cost Eco-friendly Process

  • Compared to Ferrocene, a common CNT catalyst, the PRIONE catalyst has a
    precursor price of just 1/20 (per Sigma Aldrich), making it very inexpensive

  • No additional expensive chemicals such as Thiophene,
    used in conventional CNT processes, are needed;
    only the PRIONE catalyst and a carbon precursor are required

  • The carbon precursor is also a very low-cost precursor,
    greatly reducing overall production cost, and the reaction temperature is
    far lower than typical CNT synthesis, so less production power is consumed

  • The purification process is omitted, so no purification cost is incurred,
    and therefore no environmental cost is incurred either
