NKCG supplies high-purity graphite and carbon-based materials for lithium-ion battery anodes. Its core capabilities include purification, shaping, and coating processes to produce materials with large capacity, high energy density, high recyclability, minimal volume expansion, and stable power performance at low temperatures. NKCG operates across upstream (refining raw carbon) and midstream (engineered components) segments.
High-purity graphite powders and engineered carbon- and ceramic-based materials for lithium-ion battery anodes used in EVs, consumer electronics, power tools, and renewable energy storage. Additional offerings include artificial graphite electrodes and silicon carbide fibers.
Expanded purification and coating capabilities at the Windhagen facility to ensure consistent, high-quality battery materials and supply stability for European and U.S. markets.
NKCG is a joint venture co-owned by Germany’s Kornmeyer Carbon-Group and Japan’s Nippon Carbon Co., Ltd., a publicly listed company on the Tokyo Stock Exchange.
