Mesocarbon Microbeads (MCMB) Graphite Micron Powder for Lithium-Ion Battery
Our Mesocarbon Microbeads (MCMB) Graphite Micron Powder is a high-performance synthetic carbon material designed specifically for use in lithium-ion battery anodes. Produced from petroleum pitch or coal tar, MCMB features a near-perfect spherical morphology, high carbon purity, and low surface area, resulting in excellent reversible capacity, high packing density, and minimal side reactions during charge-discharge cycles.
Thanks to its high crystallinity and particle uniformity, MCMB is widely used in commercial Li-ion battery production for electric vehicles, portable electronics, and energy storage systems.
