Lithium battery anode material MCMB high capacity, high rate and long cycle
-
AFT-MCMB-RB is an upgraded product of mesophase carbon microspheres that takes into account magnification, capacity, long cycle life, low pole piece rebound, excellent electrolyte compatibility, excellent processing performance, and excellent safety. In the process of ball formation, the method of inserting and fusing the plane molecular layers into each other is changed to make AFT-MCMB-RB form a stronger internal solid structure. After graphitization at 3200℃ ultra-high temperature, the purity of the product is improved and the impurity content is reduced. Finally, AFT-MCMB-RB is better than other MCMBs with the same particle size distribution, taking into account magnification and capacity, and has small pole piece rebound, long cycle life, excellent electrolyte compatibility, excellent processing performance, high safety, etc. Features, suitable for various types of lithium-ion batteries in power, power tools, 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.
