• In
  recognition of his leadership in SK nexilis' development of the world's best
  copper foil manufacturing technology... the highest order of industrial service
  merit in Korea

• Manufacturing
  technology for ‘the world’s thinnest, widest and longest copper foil’… selected
  as one of ‘the National R&D Excellence 100’ too

   

Kim Young-tae, CEO
of SK nexilis, a subsidiary specializing in the copper foil business for
rechargeable batteries of SKC (CEO Lee Wan-jae), received the
Gold Tower Order of Industrial Service Merit for
his contribution to leading SK nexilis' development of the world's best copper
foil manufacturing technology at the opening ceremony of the '2021 Korea
Industrial Technology R&D Exhibition' held at COEX on the 17^th.
The Gold Tower Order of Industrial Service Merit is the highest among the
medals awarded to persons of merit in national industrial development.

This award
recognizes the manufacturing technology developed by SK nexilis to produce the
world's thinnest, widest, and longest copper foil products. SK nexilis
succeeded in mass-producing copper foil with a thickness of 6 micrometers (μm)
for the first time in the world in 2013, followed by 5 μm in 2017 and 4 μm in
2019. The thinner the copper foil, the better performance and lighter weight of
the battery.

SK nexilis can
produce such thin copper foil with a width of 1,400 mm and a length of up to 77
km. The lager width of copper foil ramps up customers’ hourly battery output
and their productivity while longer lengths reduce their losses caused by roll
replacement, leading to their cost savings. SK nexilis currently has unrivaled
technological prowess to produce 77km for 6㎛ products, 50km for 5㎛
products, and 30km for 4㎛
products, all with a large width.  

SK nexilis has
also developed its own additive recipe technology. To produce thin, wide and
long copper foil, the company needs to have sophisticated techniques that can prevent
the tearing, wrinkles, etc. of the product. With its own recipes using various
additives, SK nexilis can control major physical properties such as surface
shape and quality as well as tensile strength and elongation of the copper
foil. This
raises the performance and
reliability of the
product as well as customers’
manufacturing productivity. SK
nexilis' copper foil manufacturing technology is _ eval_uated to be significantly
ahead of its competitors.

SK nexilis'
ultra-thin, wide, and long-length production technology was also selected as
one of the '2021 National R&D Excellence 100' by the Ministry of Science
and ICT earlier this month. Kim Young-tae, CEO of SK nexilis, said, “This award
is a result of the hard work and enthusiasm of all SK nexilis members, and an
external recognition of SK nexilis’ world-class copper foil manufacturing
technology,” pledging, “We will continue to do our best to increase the value
of stakeholders including customers and contribute to the development of the
Korean materials industry and battery industry.”
