CNano Technology

About

CNano Technology Limited, established in 2007 and based in Zhenjiang, China, has emerged as a leading large-scale manufacturer of multi-wall carbon nanotubes (MWCNT) for battery and composite applications, particularly focusing on the rapidly growing lithium-ion battery market. With over $100 million in funding and 200-500 employees, CNano operates high-volume production facilities in China capable of producing hundreds of tons of MWCNTs annually, serving global customers in energy storage, composites, and conductive materials markets. The company's flagship Flotube CNT products are specifically engineered for lithium-ion battery applications, where they serve as conductive additives in both cathodes and anodes. In battery electrodes, even small additions of CNTs (typically 1-3% by weight) dramatically improve electrical conductivity, enabling better power performance, faster charging, and higher energy utilization. CNano's focus on battery applications has proven strategically prescient as the electric vehicle revolution drives exponential growth in lithium-ion battery production. The company supplies CNT additives to major battery manufacturers in China, South Korea, Japan, and other countries, with its products incorporated into millions of battery cells for electric vehicles, consumer electronics, and energy storage systems. CNano's MWCNTs are produced through catalytic chemical vapor deposition processes optimized for consistent quality, controlled diameter distributions, and surface properties tailored for battery applications. The company has developed various MWCNT grades including long nanotubes for maximizing electrical percolation, short nanotubes for easier dispersion, and surface-treated variants for specific battery chemistries. Beyond batteries, CNano targets composite materials applications where MWCNTs enhance mechanical strength, electrical conductivity, and thermal properties of polymers and elastomers. The company's products are used in automotive components, industrial materials, and consumer goods requiring electrostatic dissipation or EMI shielding. CNano has invested significantly in production scale-up and cost reduction, recognizing that commercial success in high-volume applications requires not just technical performance but also competitive pricing. The company's position in China provides proximity to the world's largest battery manufacturing ecosystem and access to the supply chains driving electric vehicle adoption. CNano has established quality management systems meeting automotive industry requirements, ensuring consistent material properties across large production volumes. As China has become the dominant force in lithium-ion battery production, CNano has benefited from being embedded in this manufacturing ecosystem, providing localized technical support and rapid response to customer needs. The company represents the emerging class of Chinese nanomaterial manufacturers achieving global scale, demonstrating how nanotechnology production is globalizing with significant capacity concentrated in Asia's manufacturing centers.
