Synthetic Graphite Mesocarbon Microbead (MCMB) Anode
CAS Number: 7782-42-5
Mesocarbon microbead (MCMB) synthetic graphite anode material offers isotropic structure, excellent rate capability, and superior cycle stability compared to natural graphite, making it the preferred choice for high-power and high-cycle-life applications such as power tools, HEV, and aerospace batteries.
Technical Specifications
| D50 (μm) | 15–25 |
| appearance | Black spherical powder |
| purity (%) | ≥99.95 |
| tap density (g/cm³) | 0.80–1.05 |
| BET surface area (m²/g) | 1.5–3.5 |
| first-cycle Coulombic efficiency (%) | ≥91 |
Applications
- High-power tool battery anode active material
- HEV/PHEV battery anode requiring high rate capability
- Aerospace and military battery anode
- NMC-paired anode for >2000 cycle EV batteries
- Blended MCMB/natural graphite anode formulation
Key Features
- Isotropic particle structure ensures uniform lithium intercalation and minimal swelling
- Very low BET (1.5–3.5 m²/g) minimizes irreversible capacity loss and electrolyte consumption
- High rate capability enables 5C continuous discharge with minimal capacity fade
- Consistent batch quality (tight D50 and tap density) for reproducible electrode manufacturing
