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

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.
