- Long cycle life
- Improve mechanical properties, better adhesion of electrode materials
- Replacing carbon material (Carbon black, Carbon fiber, etc.) in battery
* Single-wall CNT DUKSAN Suspension
BASE Solution : N-Methyl-2-pyrrolidone, NMP
CNT Content : 0.2 ~ 0.4 %
* Multi-wall CNT DUKSAN Suspension
BASE Solution : N-Methyl-2-pyrrolidone, NMP
CNT Content : 2.0 %
- 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% )
