Cathode and MLCC release-film maker
Cosmo Advanced Materials & Technology
Cosmo Advanced Materials & Technology makes high-nickel NCM cathode active material for lithium-ion batteries and release film for MLCC production. In its 2025 fiscal year revenue was 456.3 billion won, with cathode at 71.8 percent and functional film (release film and toner) at 28.2 percent. It supplies cathode to LG Chem and Samsung SDI, and MLCC release film to Samsung Electro-Mechanics. It buys lithium from Albemarle and SQM and NCM precursor from China's CNGR and Huajin, with raw-material prices tied to global benchmarks (LME and FMB). An EV demand lull hit cathode sales, and the company is betting on single-crystal high-nickel cathode for a turnaround.

Cosmo Advanced Materials & Technology operates across Cathode and MLCC release-film maker. It remained weak at -3.4% in 2025 and -23.5% in 2026. The supply side (avg +8.5%) has moved harder than the stock (-23.5%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is Samsung Electro-Mechanics (+402.2%) and the furthest behind is Albemarle (-10.3%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. An EV demand lull hit cathode sales, and the company is betting on single-crystal high-nickel cathode for a turnaround.
