The Crate performance of CNT and Super P was analyzed from to 5 C. In the first C and C, the capacity of CNT cell was slightly higher than Super P cell, and at 1 C both cells showed the same capacity as 147 mAh g −1. After 2 and 5 C, when the current density returns to 1 C, both cells returned their capacity.

Therefore, it is necessary to rationally control the processing parameters to effectively disperse CNT in polymer matrix and avoid the cutting length of CNT and polymer. Although the ball mill is a promising technique used to disperse CNTs in different medium, the mechanism of exfoliation of CNTs should be explored in depth. Melt Extrusion Process
