Carbon Nano Tube

CNT

Carbon Nano Tube

Good dispersion of Silicon and C confirmed through EDS mapping
Applying this composite as a conductive additive maximizes efficiency
An advanced material currently drawing attention across various industries thanks to its
excellent mechanical properties, electrical selectivity, field emission characteristics, and high-efficiency hydrogen storage capability

CNT

Low-cost Carbon Nano Tube (CNT) Manufacturing Technology Using Alkali Metals

Existing CNT Manufacturing Technology

Uses organometallic compounds such as Fe, Ni, and Co as catalyst metals
Limited reserves result in high costs
(Ni: $14,000/ton)
Requires an acid treatment process using acidic solutions such as sulfuric and nitric acid
Poses process safety issues, contaminant disposal problems,
and high costs

Developed CNT Manufacturing Technology

Uses water-soluble alkali metals (Na, K, etc.) as catalyst metals
Low-cost and infinitely extractable from seawater
(Na: $150/ton)
No acid treatment process required, reducing process cost
Enables manufacturing of 'high value-added' CNT

CNT

Target Technology (Feasibility)

A sodium chloride solution is applied within the solution to form nanoparticles, which are then
sprayed into a high-temperature thermal treatment reactor and grown into continuous MWCNTs
The absence of transition metals provides stability against explosion and fire
An innovative process that overcomes the key drawbacks of the fluidized bed reaction, currently the main mass-production method, namely the costly reducing agent
and the high-cost batch (non-continuous) manufacturing process required for support loading and removal
Delivers superior performance with low damage to the product
