- Key Products/Technologies
- The company possesses SWCNT (Single-Walled Carbon Nanotube) synthesis technology utilizing FC-CVD equipment. This equipment is a result of their independently developed horizontal CVD technology based on the Floating Catalyst method. This technology achieves 7 times higher SWCNT production speed and over 30% higher price competitiveness compared to competitors. In 2025, the company introduced high-quality SWCNT and began supplying SWCNT for dispersion. Plans include establishing a pilot plant with an annual production capacity of 210kg in 2026 and mass production of 13 tons annually by 2028.The company possesses SWCNT (Single-Walled Carbon Nanotube) synthesis technology utilizing FC-CVD equipment.

- Single-Walled Carbon Nanotubes (SWCNTs) are fibrous conductive materials with a diameter of 1-2nm. They are high-performance additives that reduce the amount of conductive material by 1/5 compared to MWCNTs, simultaneously increasing the content and lifespan of cathode and anode materials. The company demonstrates the ability to synthesize high-quality SWCNT with 65% purity and an IG/ID ratio of 35. Developed since 2023, these products are currently available for research purposes.Single-Walled Carbon Nanotubes (SWCNTs) are fibrous conductive materials with a diameter of 1-2nm.

- Silicon-Carbon composite anode material involves core technology for uniformly precipitating nanosized silicon crystals, 6 nanometers (nm) in size, into an amorphous silica (SiO2) matrix to form a SiOx structure. This advanced material can increase the charge/discharge capacity of lithium-ion secondary batteries by up to 50%. The company is developing products that reduce initial irreversible capacity by 20% and ultimately by 30%. It enables the production of anodes capable of storing over 570mAh/g of lithium by replacing up to 15% of graphite. The spheroidized micro-powder (Code: ES-2000) is easy to replace graphite due to its similar size and does not require changes to existing binders and conductive agents. Development of silicon anode materials began in 2020, with a mass production system of 36 tons per year established in June 2025, and production capacity is currently being expanded to 150 tons.Silicon-Carbon composite anode material involves core technology for uniformly precipitating nanosized silicon crystals, 6 nanometers (nm) in size, into an amorphous silica (SiO2) matrix to form a SiOx structure.

- SWCNT+DWCNT hybrid type offers intermediate performance between SWCNT and MWCNT, with the significant advantage of being producible at 1/4 the cost of SWCNT using a CVD process similar to MWCNT. The company possesses manufacturing technology utilizing iron, cobalt, and mixed catalysts. Currently, the supply of SWCNT+DWCNT hybrid is temporarily suspended to focus on the FC-CVD SWCNT business.SWCNT+DWCNT hybrid type offers intermediate performance between SWCNT and MWCNT, with the significant advantage of being producible at 1/4 the cost of SWCNT using a CVD process similar to MWCNT.
