Product description
High carbon graphite MCMB (mesocarbon microbeads) is a high - performance material designed for lithium - ion battery anodes. Its spherical structure achieves a tapped density of 1.211g/cm³, significantly enhancing electrode packing density. With an initial discharge capacity of 340.5mAh/g and a first - cycle efficiency of 94.3%, coupled with a fixed carbon purity of 99.959%, it ensures stable long - cycle life. Accurate particle size control (D50 = 16.342μm) and low moisture content (≤0.035%) make it suitable for the high - rate charge and discharge requirements of power and cylindrical batteries. The optimized specific surface area of 1.165m²/g balances lithium - ion diffusion efficiency and side - reaction inhibition. Packed in a standard 500g/bag, samples are available for trial use. It is applicable in fields such as new energy vehicles and energy storage systems, meeting the requirements for high - energy - density and durability.

FAQ
Q1: Does a D90 particle size of 27.019μm affect electrode coating uniformity?
A: With a D50 of 16.342μm, the particle size distribution is optimized for coating processes. Actual coating uniformity meets industry standards for power batteries, avoiding agglomeration or uneven porosity.
Q2: Is the High carbon graphite re - drying needed after opening the material?
A: Moisture is strictly controlled below 0.035% at delivery. It's recommended to store it sealed after opening. If exposed to humidity above 60% for over 48 hours, vacuum - dry at 80℃ for 4 hours before use.
Q3: Is High carbon graphite suitable for silicon - carbon composite anode systems?
A: The high carbon graphite spherical structure serves as an ideal carrier for silicon - based materials. High tapped density and low specific surface area can alleviate silicon expansion stress. Technical support for specific composite solutions is available.
Q4: What's the actual cycle decay rate with a first - cycle efficiency of 94.3%?
A: After 1000 cycles of 1C charge and discharge, capacity retention is over 88%. High fixed carbon purity and low surface defects contribute to better cycle stability than regular graphite anodes.
Q5: What's the minimum order quantity for samples?
A: 500g/bag samples are available to meet laboratory - scale electrode - making needs. Contact customer service for the application process.
