Lithium battery anode material MCMB high capacity, high pressure, high energy density
-
AFT-MCMB-GR is an upgraded product of mesophase carbon microspheres with high capacity, high pressure, long cycle, excellent electrolyte compatibility, excellent processing performance, and high safety. After AFT-MCMB-GR has passed high temperature graphitization , Improve the purity of the product, reduce the impurity content, and then undergo the modification technology of mesophase carbon microsphere morphology, so that AFT-MCMB-GR has a higher capacity and higher compaction than ordinary MCMB. It also takes into account the long cycle life of MCMB, excellent electrolyte compatibility, excellent processing performance, and high safety. It is suitable for various types of lithium-ion batteries in power, energy storage, 3C digital and other fields.

Storage Condition
1、Suggest storage temperature and humidity controlled below 40 ℃ and 60 %RH, respectively, for brandnew; After opening, please use it up as soon as possible.
2、After opening for 1 hour, it is a natural phenomenon for moisture regain, implying that moisture content of powder could be increased to 3000 ppm. Suggest drying it again before use.
