TUBALL™ FOIL is OCSIAl’s product bringing unique advantages of single wall carbon nanotubes to Li-ion battery manufacturers.
Announced in Aug 2015, TUBALL™ FOIL is aluminum or copper foil coated by very thin layer of OCSiAl’s single wall carbon nanotubes for use as a current collector in Li-ion batteries.
Key benefits of TUBALL™ FOIL are reduced impedance and improved adhesion with virtually no additional thickness. Thickness of conductive layer is <50nm.
This property is unique to SWCNT, as no other conductive additive can be coated at this thickness and provide the same benefits.
To replace thicker carbon coated aluminum or copper foil, increase cell capacity
to improve power of a batery pack
to increasse low temprature performance
to improve adhesion, decrease amont of PVDF
to extend cycle life
to improve discharge rate performance
