CNano Technology's product portfolio is centered on sophisticated conductive additives and masterbatches, with a primary focus on improving conductivity in energy storage and other advanced materials applications. The company???s offerings can be categorized as follows:
Nano-Scale Carbon Materials
The raw materials and base products manufactured by Cnano Technology include:
- Carbon Nanotubes (CNT) Powder: The company produces various grades of carbon nanotube powder, which serve as the fundamental building block for their other products. These powders possess superior electrical conductivity and mechanical properties. Specifications vary, including different average diameters (e.g., 1.7-2.7nm, 7-11nm, 10-25nm), purities (up to 99.9%), and lengths, such as the high-purity MWCNT FT6000 and the ultra-conductive Single/Double wall CNT FT2000.
- Graphene: The company is also committed to the R&D and production of graphene, often integrating it with carbon nanotubes to create composite materials with enhanced performance.
Ready-to-Use Conductive Products
The majority of Cnano Technology???s commercial success comes from its highly dispersed, ready-to-use formulations:
- Carbon Nanotubes Conductive Paste (Slurry): This is the company???s main product and is a visionary development utilizing their proprietary CNT technology. The paste is a specialized dispersion designed to be easily incorporated into battery electrode manufacturing processes. Its unparalleled conductivity helps reduce energy loss, significantly improving the performance of lithium-ion batteries by enabling energy transfer at an efficient rate.
- Graphene Composite Conductive Paste (Slurry): A combination of carbon nanotubes and graphene dispersed in a paste format, offering synergistic conductive properties for specific high-performance applications.
- Carbon Nanotubes Conductive Masterbatch: This product is a conductive plastic composite containing a high concentration of carbon nanotubes (typically 15-20%). The masterbatch is designed for easy let-down (dilution) by customers, forming a conductive network that provides superior electric conductivity in the final plastic or rubber part at very low loading rates (as low as 2-4%).
Commercial Applications
The application of Cnano Technology's nano-carbon materials is concentrated in fields demanding high electrical conductivity and mechanical reinforcement:
- Lithium-Ion Batteries and Electric Vehicles (EVs): This is the most critical commercial application, directly supporting the alternative energy solutions sector. The carbon nanotube conductive paste acts as a conductive additive in the battery's cathode or anode, which is vital for advancing battery technologies. The improved conductivity translates directly to greater vehicle range and faster charging speeds for electric vehicles, which is a major focus for global EV manufacturers.
- Conductive Polymer Composites: Their CNT-based products, including masterbatches, are used to create polymer materials with high electrical conductivity for various electronic and industrial uses.
- Antistatic Coatings: The conductive properties of the nano-carbon materials are utilized in coatings to dissipate static electricity, an essential requirement for electronic components and sensitive environments.
- Tire and Rubber Reinforcement: The mechanical and reinforcing properties of carbon nanotubes are used to enhance the strength and durability of tire rubber and other elastomer products, in addition to imparting conductivity.
The company's involvement in setting the national standard for carbon nanotube conductive paste (GB T33818-2017) underscores its leadership and technological influence in its specialized market. Furthermore, Cnano Technology has expanded its reach with overseas operations, including Cnano Technology Europe GmbH and Cnano USA, to serve international customers and address the global demand for advanced energy solutions.
