Products Description
The graphite anode has reached the maximum theoretical capacity, and the silicon anode has the highest specific capacity among the anode materials. However, the cost of silicon-based anode is currently too high (more than 3 times that of ordinary graphite). At present, the mainstream solution is to mix silica and silica carbon with graphite and then use, and the conventional gram capacity models are 400, 407, 420, 450, 550, 650mAh/g.
