Battery Grade High Purity Multi Walled Carbon Nanotubes (MW-CNTs) and Carbon Nanofibers (CNFs)

Product Details:

These carbon nanotubes (CNTs) and carbon nanofibers (CNFs) from MSE Supplies have very high purity (>99.0% or 99.9%) by controlling the catalyst impurity level to be below 1% or even 0.1% through proprietary purification processes.

Battery Grade multi walled carbon nanotubes (MW-CNTs) and carbon nanofibers (CNFs) are built from sp² carbon units and present a seamless structure with hexagonal honeycomb lattices, being several nanometers in diameter and many microns in length. MW-CNTs and CNFs are commonly synthesized by chemical vapor deposition (CVD) and the diameter of carbon nanotubes can be controlled by deposition conditions, such as metal catalyst material, temperature and carbon precursor feed speed.
