SWCNT Water Dispersion for Anode Materials
The market is increasingly adopting silicon anode materials to improve the energy density of secondary batteries.
Extreme volume expansion of about 300% during charge/discharge causes the electrode structure to collapse. SWCNT is emerging as a material to address this.

Primer Coating Solution
Primer coating is a key material that improves various performance aspects of secondary batteries and enhances the completeness of next-generation batteries
Dramatically lowers the interfacial resistance between the current collector and active material during fast charging (improving charging efficiency and speed)
Contributes to extending battery lifespan (improved resistance to physical expansion and contraction)
Supports optimization of energy density
