Our Line-up with Main Application

cnt

Application for Lithium-ion Battery

Conductive agent for Cathode & Anode

- Long cycle life
- Improve mechanical properties, better adhesion of electrode materials
- Replacing carbon material (Carbon black, Carbon fiber, etc.) in battery

Conductive agent for Cathode

cnt

* Single-wall CNT DUKSAN Suspension

BASE Solution : N-Methyl-2-pyrrolidone, NMP
CNT Content : 0.2 ~ 0.4 %

cnt

* Multi-wall CNT DUKSAN Suspension

BASE Solution : N-Methyl-2-pyrrolidone, NMP
CNT Content : 2.0 %

Conductive agent for Anode

- Volume resistance decreased ( Powder Resistance for Electrode Slurry )
- Increase energy density due to high percent of active material in battery electrode
- Multi-wall Suspension : High purity carbon material ( Fe free, Metal impurity < 1% )
