Product Details
Product Description:
The product is designed as a new-type of aluminum foil current
collector with uniform coating of graphene on its surface. Based on
the excellent electrical and two-dimensional layer structure of
ultra-thin layer with a thickness of less than 0.5μm on the surface
of aluminum foil has high electrical conductivity,which
significantly reduces the interface resistance,
Product Features:
Ø UItra-thin coating composed of graphene. Ø Reducing the
interface resistance to improve rate capability and cycle life of
L-ion battery and super capacitors. Ø Improving the adhesion
between active materials and current collector and reducing the
corrosion of current collector Ø Enhancing the safety of batteries
by reducing polarization and alleviating the heating-up during
charging.
Application:
Ø Lithium-ion batteries Ø Super capacitors
Specification:
Appearance | Coating Thickness (double side)/μn | Areal density (double side)/mg cm-2 |
Dark gray coating | Typically 0.5 | 0.04~0.1 |
Usage and storage:
Ø Use the product in the workshop with humidity of ≤20%RH and a
high dust purification. Ø Store the product below 35℃, do not open
the vacuum package before use .after use ,the left product should
be dried at 400℃ for 2 hours under vacuum ,then kept in the
cabinet filled with nitrogen at room temperature. Ø The product
