SK Nexilis introduces carbon-coated copper foil for batteries
On October 20, 2026, SK Nexilis unveiled a carbon-coated copper foil designed to enhance battery stability and efficiency.
SK Nexilis, a subsidiary of SKC specializing in battery copper foil, introduced a carbon-coated copper foil for batteries on October 20, 2026. This technology aims to improve the adhesion between copper foil and anode materials, thereby increasing electrode stability. The announcement was reported by MarketScreener on October 21.
According to SK Nexilis, the special carbon coating is intended to prevent delamination of electrode layers. This effect is becoming increasingly important as a higher silicon content in anode materials can enhance battery energy density, while also increasing volume changes during charging and discharging.
The foil is also suitable for dry processes in battery manufacturing, which can reduce energy consumption and production costs. SK Nexilis is initially setting up a pilot production system to verify process stability, with commercialization planned for the second half of 2027.
This development strengthens SKC's profile as a provider of materials for batteries and modern electronics. However, a tangible revenue or profit impact from this announcement cannot yet be determined, as pilot production and scaling are still pending. For investors, the focus will primarily be on the technical implementation by 2027.
SKC is a South Korean chemical and materials company with business areas in chemical products, copper foil for lithium-ion batteries, semiconductor materials, and PBAT. Its products are used in electric vehicles, energy storage, IT devices, semiconductors, and packaging. SK Nexilis connects SKC's battery and electronics materials with a broader chemical business, positioning itself between specialized foil manufacturers and diversified materials companies.
The market environment for South Korean material stocks can be found in KOSPI.
