12um High - Grade Large Capacity Lithium Battery Dedicated Copper Foil
Product Description
- Nominal thickness of 6 to 20 microns single-sided, double-sided, MAO please both parties lithium ion battery is special electrolytic copper foil, breadth of product range 100-1300 - mm.
- The double photoelectric solution of copper foil with double structure symmetry theory, the density of metal close to copper, surface profile of a very low density, high elongation and tensile strength characteristics; With single-sided, double-sided MAO compared with electrolytic copper foil, lithium battery anode materials with the paste, a doubling of contact area, can significantly reduce the negative fluid and anode materials, the contact resistance between the increase the volume of a lithium ion battery capacity and structure of symmetry, and double photoelectric copper foil negative set fluid has good resistance to heat and cold expansion performance, can significantly extend the service life of battery.
