8um Battery Ultra Thin Copper Foil High Flexibility / Extensibility

 

Ultra thickness 8um high precision electrodeposited copper foil for Li-ion battery
 

Produict Information :

We can provide the specific single matte.double matte,and double shiny ED copper foil with the nominal thickness from 8um to 35um for the li-ion battery;the width is from 100mm to 1300mm.and the double shiny ED copper foil has the characteristics of the both sides.

 

Features​

1. the metal density nearing the copper theoretical density,very low surface profile,and high elongation and tensile strength;

2. comparing with the single-matte and double matte ED copper foils,when it adheres with the cathode materials,the contact area will increase dramatically,

3. it can distinctly reduce the contact resistance between the cathode current collector and the cathode material;the cathode current collector of the foil also has excellent resistance of the cold and heat expansion,

4. it can obviousely increase the service life of batteries.

 

  (1) High flexibility and extensibility
  (2) Even and smooth surface
  (3) Good fatigue resistance
Performances (4) Strong antioxidant properties
  (5) Good mechanical properties
  (6) The material has higher extensibility
  (7) It has a high bending resistance
  (8) It has no crack.
