Environment
CCUS* Water
Carbon Capture, Utilization, Storage
We are developing technologies for the environment, including a solution for pollution from battery waste due to the growing electronic vehicle market, reducing carbon dioxide, the cause of global warming, and purifying and reusing the wastewater from industrial processes.
Plastics & Solutions
Plastic Recycle Packaging Solutions Lightweight Material Solutions
We are contributing to the establishment of a plastic circular economy by recycling 100% of the plastic our company produces and expanding eco-friendly products.
Petroleum/lubricating oil
Aromatic & olefin New catalyst and process
We independently developed new catalysts and processes, such as aromatic switching catalysts and the process, as well as the catalyst that can switch aromatic by-products to high-value xylene, contributing to the establishment of the nation's largest scale PX production.
Petroleum/lubricating oils
Eco-friendly Raw Materials/Products Eco-friendly Asphalt
Waste Lubricating Oil Recycling e-Fluids
We are developing eco-friendly petroleum/asphalt/lubricating oil products and are working on developing recycling technology for waste asphalt and waste lubricating oil. We are also developing lubricating oil for electronic vehicles.
Intelligence and electronic materials
Lithium-ion Battery Separator Display materials
We are the first in the nation to have independently developed a lithium-ion battery separator, and we also acquired our own production and coating technology for transparent PI film, the main material for flexible displays, to apply to the whole display material area.
Field of research and key projects at the Battery Laboratory

As a global leading player, SK On has been continuously working on battery R&D to keep up with the increased demand for electronic vehicles and stay abreast of technological trends. As a way of creating social value through eco-friendly products, we also developed high-efficiency, high-capacity lithium-ion batteries to minimize air pollution. Moreover, we are working on securing the quality of electric power and the safety of electrical grids, and developing new renewable energy-linked energy storage devices.
