Research Development

The development of advanced technologies and new materials go hand-in-hand. SK Innovation has been developing a range of new materials in energy areas and information and electronics areas based on its expertise in polymers and petrochemicals. We have successfully developed and brought to market world-class new materials such as lithium ion battery separators, flexible copper clad laminates, and optical film thus contributing to local production of core components and establishing the technological foundation for the company. With our commitment to new materials, we are prepared to open a new horizon in the advanced materials sector.

Major R&D Project

Lithium-ion Battery Separator (LiBS)
A lithium-ion battery separator (LiBS) is a key component used in lithium-ion batteries and a functional polyolefin film that prevents physical contact between electrodes to maintain stability and allows lithium-ions to pass freely during battery charging and discharging. SK Innovation became only the world’s third company to successfully develop and commercialize proprietary technology for LiBS, and we are now producing top-quality products. We remain committed to helping Korea sharpen its competitive edge in the battery market and develop rechargeable batteries, a next-generation growth driver, by providing superior products and technologies tailored to customers’ needs.

Flexible Copper Clad Laminate (FCCL)
As mobile phones, digital cameras, laptops, and other portable electronic devices grow
slimmer and lighter, the focus is now placed on thin, highly integrated and highly flexural circuit boards. Demand is also increasing for new materials that can replace existing circuit boards. SK Innovation has developed flexible copper clad laminate, or FCCL, a core component of the flexible printed circuit boards used in many consumer electronic devices.
We have developed and built a mass production facility using our proprietary continuous curing technology, and provided products with world-leading dimensional stability and bending resistance, supporting an array of designs for electronic devices.

FCW (Flexible Cover Window)
SK Innovation has developed FCW(Flexible Cover Window), the core material of flexible displays, with its own technology. Its major properties that decide the qualities of FCW are as followed; flexibility, impact resistance, high strength and scratch resistance correspondingto tempered glass. In order to increase those properties, we have secured various technologies like PI polymerization technology, optical film coating technology and hard coating technology. We have developed products with high transparency, flexibility(Bending), strength(Hardness) and scratch resistance(Anti-scratch) by complementing the properties of transparent PI and HC. We are supplying FCW products, which have secured SCM of PI and HC, to domestic and overseas panel makers and are recognized as excellent properties
