SK Nexilis, a subsidiary of SKC, says it developed carbon-coated copper foil that improves adhesion between the anode material and the current collector. The target is silicon anodes, which swell during charging and can lose contact with the foil. Stronger adhesion could keep the electrode structure stable and extend battery life. The company also says the coating works with dry electrode manufacturing, a process that avoids liquid solvents and heavy drying ovens. The company plans to build a pilot production line and verify process stability before aiming for commercialization in the second half of 2027. That timeline matters because high-silicon anodes and dry electrodes are both seen as key steps for cheaper, higher-energy batteries in EVs and grid storage. If the coating holds up in real cycle testing, it could reduce manufacturing energy use and extend the useful life of battery packs.
