Pre-order

Copper foil is coated with a 10-30 nm layer of TUBALL™ graphene nanotubes on both sides. The nanotube layer on the copper foil lowers interface impedance and improves charge acceptance. It improves adhesion of electrode material to metal foil by up to three times, allowing production yields to be improved and the percentage of electrode binder to be reduced.

Benefits

Allows Welding

Welding is possible through the coating

High Energy Density

Preserves and even increases high energy density

Improves adhesion

Improves adhesion of electrode material to metal foil by 3 times, allowing the percentage of binder to be reduced

Ultrathin

Less than 50 nm per side
