The lithium copper foil is made of conventional copper foil and lithium metal belt after composite welding, which can be coated with lithium on one side or both sides.
Appearance
Lithium strip surface flat, bright, no oil spots, no perforation and tear.
No visible oxides and nitrides.
There should be no wrinkles, holes, cracks, creases, pressing lines and other defects.
The edges of the lithium copper foil should be neat and without cracks.
The lithium copper foil shall not have delamination and inclusion.
Cleanliness : Lithium foil is uniformly silver colored.
