Lithium battery anode material artificial graphite fast charging type 5C rate charging
-
AFT-AGBL is an artificial graphite that takes into account capacity, rate and cycle life. After high temperature graphitization, the purity of graphite is improved and the impurity content is reduced. After the surface modification technology of artificial graphite is processed, the compatibility with electrolyte is improved. It has high capacity, high rate, long cycle and other performances. It is suitable for various types of lithium ion in the fields of fast charging, power EV/HEV/PHEV, start-stop power supply, energy storage, 3C digital, etc. battery.

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.
