(2)Features and Applications
It is made by imported prime quality needle coke and domestic petroleum coke by processing of extruding, baking, graphitization, breaking and sphercizing and so on. Spherical artificial graphite negative raw material has features of similar ball shape, narrow distribution, good absorption, high power contain capacity, stable quality, good between-bath consistence and cyclicity, good tap density of over 1.55g/cm3.
It is suitable for making square shape, cylinder shape and li-ion polymer battery.
