Carbon nanotubes is a promising hydrogen storage material, it has high hydrogen storage capacity, can be repeated to put the reversible process of hydrogen absorption;As electrode materials for lithium-ion battery, carbon nanotubes have higher intercalated-li capacity and better cycle performance than that of graphite.Fuel cell catalysts made of carbon nanotubes deposition on the noble metal, can reduce the dosage of precious metals, to reduce the catalyst particle size and improve the performance of catalyst.

Statistics show that in 2015 the national battery industry accumulative total revenue was 447.4 billion yuan, the main products are lithium battery business income 203 billion yuan.To date, most commonly used batteries are composed of toxic substances, such as lithium. lithium resources are limited, not only difficult to handle, but flammable.carbon nanotubes batteries are completely non-toxic, and can keep stable indefinitely,never mind electric leakage. huge potential is obvious for future application.

Here sells purest and cheapest Carbon Nanotubes in the world. Carbon nanotubes is available with different purity grades and surface functionalization. Carbon Nanotubes is produced by Chemical Vapor Deposition (CVD) method by HW NANO and depending on the diameter one can obtain either single-walled Carbon Nanotubes(SWCNTs) ,double-walled carbon nanotubes (DWCNTs)or multi-walled Carbon Nanotubes (MWCNTs). Our current capacity for the production of MWCNTs far exceeds that of other suppliers.

Spec of carbon nanotubes:

1) SWCNT: diameter: 2nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%

2) DWCNT: diameter: 2-5nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%

3) MWCNT: diameter: 8-20nm,30-60nm,60-100nm, Length: short tube 1-2um and long tube 5-20um, purity: >99%

4) Low purity for the three ones above are all available.

5) Functionalized carbon nanotubes: COOH-CNTs, OH-CNTs, Amino-CNTs, Metal coated CNTs...

6) Dispersion: CNTs water dispersion, and CNTs oil dispersion.
