technique
reduction and productivity
improvement of our customers. -
Constant thickness
SK Nexillis offers the world's
and uniform surface
most reliability. -
Thickness
6 to 20µm
Improve the productivity in manufacturing
lithium-ion batteries with high-strength properties
at room temperature and improve reliability of lithium-ion
batteries with high-softening characteristics
after thermal hysteresis
-
High tensile strength properties at room temperature
The handling ability of the customer's battery manufacturing process is excellent to prevent wrinkles, tears and surface bleeds. -
Inhibition of copper
After the battery is manufactured,
foil breakage
it changes to high-softening properties to suppress the kinetic breakage of the battery in charge and discharge. -
Usefulness of applying
It is also useful for the applying
live-metal materials
metallic materials such as Si or Sn. -
Thickness
6 to 10µm
Our battery copper foil improves productivity within
manufacturing of lithium-ion batteries with its high
intensity and high heat resistance, while ensuring
safety during battery charging/discharging process
at the same time.
-
High tensile strength characteristic at room temparature
Excellent handling within the battery pole plate manufacturing process, with high resistance to wrinkles and fractures, along with less vulnerability to property change during heat treatment -
Prevention of cathodic deformation
This prevents deformation of the
cathode caused by the expansion of the volume of the cathodic material even after heat treatment, increasing the reliability of the battery. -
