Our HD-CNT or LL-CNT are annealed at 3,000℃, so that super high crystallization of CNT are obtained (see the following Raman spectrum).
This will be useful as conductive additives, especially in electrode materials of LIB. When SC-CNT is added into Si-based negative electrode materials of LIB, its graphite-like high crystallization gives not only high conductivity, but also high strength and rigidity, which will lead to reasonable improvement of cycle performance of LIB.

The lower peak on the right is the D band, the G band is on the left, the highest peak on the left is the 2D band
