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 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
