Nippon Carbon Co., Ltd. (est. 1915, Tokyo) produces synthetic graphite anode materials, artificial graphite electrodes, carbon fibers and silicon carbide fibers. Products serve EV batteries, semiconductors, steelmaking and energy storage.
Nippon Carbon’s core technology centers on synthetic/artificial graphite production and carbon-material processing to produce anode materials with high reversible capacity, low volumetric expansion during cycling, strong power delivery, and improved low-temperature behavior. The company also produces high-purity graphite for semiconductor and electrochemical uses, artificial graphite electrodes for electric-arc furnaces, carbon fibers, and silicon carbide continuous fibers. Differentiators include controlled feedstock processing, integrated manufacturing scale, and formulations optimized for recyclability and thermal stability. Supporting capabilities include in-house R&D, pilot-scale production, and partnerships for feedstock supply and process integration that enable consistent quality and reliable supply to battery and industrial customers.
Nippon Carbon supplies artificial graphite anode materials for lithium-ion batteries, artificial graphite electrodes for steelmaking, high-purity and specialty graphite, carbon fibers, silicon carbide continuous fibers, and impervious graphite (RESBON®). Benefits include high capacity, recyclability, low expansion, thermal and chemical resistance, and consistent quality from integrated manufacturing. Products serve EVs, consumer electronics, energy storage systems, steelmakers, semiconductor fabs, aerospace, and chemical processing equipment manufacturers.
