High Capacity Anode for Rechargeable Batteries

Zeptor is the proud recipient of R&D 100 Award.

Zeptor has developed a high speed roll-to-roll process which creates 3D nano-forest structure, Carbon Nano Fiber (CNF), on a thin metal foil.  Anchoring CNF into the metal foil, Zeptor creates robust CNF and metal composite.  This unique material is applicable to current collector for rechargeable batteries which include solid state batteries. 


  • Superior mechanical strength of anchored CNF

  • Strong adhesion with extra large surface area

  • High electrical conductivity

  • High thermal conductivity

  • Low production cost by high speed roll-to-roll process which is done in room temperature and ambient atmosphere
