With the rapid development of electric vehicles, solid-state batteries, energy storage systems, and high-performance lithium-ion batteries, single-walled carbon nanotubes (SWCNTs) are gradually emerging as a next-generation conductive additive technology due to their exceptional electrical conductivity, high aspect ratio, and ability to form stable conductive networks. An increasing number of battery companies are establishing SWCNT production lines, driving conductive materials from laboratory research and development toward industrial applications.
However, achieving large-scale SWCNT manufacturing requires far more than simply realizing nanotube synthesis. The key challenges lie in achieving continuous and stable growth, high-purity powder purification, uniform slurry dispersion, and integrated engineering delivery of the entire production system.
These processes directly determine product quality, batch consistency, and final electrochemical performance, making them critical challenges in the industrialization of SWCNT technologies.
1. Competition in industrialization is shifting from “growth technology” to “Integrated Production capabilities.”
In recent years, industry attention toward FCCVD continuous growth technology has continued to increase. Compared with conventional synthesis methods, FCCVD (Floating Catalyst Chemical Vapor Deposition) offers advantages including continuous operation, high productivity, and strong scalability, making it one of the key technological pathways for the industrial production of SWCNTs.
However, for industrial-scale manufacturing, FCCVD synthesis equipment alone is not sufficient. From powder collection, purification, and material handling to slurry preparation and dispersion, every process step can influence the structural integrity, dispersion characteristics, and electrical performance of SWCNTs.
Especially during slurry preparation, SWCNTs are highly prone to entanglement and agglomeration due to their nanoscale structure and extremely high aspect ratio. Without precise dispersion control, agglomeration may reduce slurry uniformity and potentially damage nanotube structures, negatively affecting the formation of conductive networks within battery electrodes. Therefore, more companies are increasingly seeking integrated solutions covering the complete SWCNT manufacturing process, from synthesis and purification to slurry production.
2. From SWCNT Synthesis to Conductive Slurry Production, Boyee Enables Turnkey Production Line Delivery
To address the industrialization requirements of SWCNT technologies, Boyee has developed an integrated solution covering: FCCVD continuous growth systems, SWCNT powder purification systems, Conductive slurry production lines, Turnkey EPC project delivery. This solution provides customers with comprehensive technical support from laboratory validation and pilot-scale process development to industrial-scale production deployment.
During the FCCVD continuous growth process, Boyee utilizes a proprietary optimized growth technology. By precisely controlling the feeding of carbon sources and catalyst precursors, suspended catalyst particles are generated under high-temperature conditions, enabling continuous SWCNT formation on catalyst surfaces. Combined with a continuous collection system, the process enables stable, uninterrupted production.
The integrated system incorporates: Multi-stage ultrasonic atomization feeding technology, Preheated gas delivery system, Explosion-proof, water-cooled stainless-steel reactor system, Large-diameter continuous collection mechanism. These technologies ensure stable reaction conditions, continuous operation, and consistent product quality, enabling the production of high-purity SWCNT powder with excellent structural characteristics.
Due to the strong entanglement characteristics of SWCNTs, achieving uniform dispersion is one of the critical challenges in practical applications.To address this challenge, Boyee has developed a dedicated SWCNT slurry production system integrating: Colloid mill pre-dispersion, High-pressure homogenization, Recirculating dispersion technology. The continuous production process covers: Feeding, Pre-dispersion, Fine dispersion, Rheological adjustment. While effectively breaking down SWCNT agglomerates, the process minimizes nanotube structural damage and material loss. The final conductive slurry features: Uniform dispersion, Reduced large-particle content, Low impurity levels, Excellent storage stability, Improved conductive network formation capability.
3. It's not just about the equipment—it's about our engineering capabilities.
As the SWCNT industry moves toward industrial-scale applications, customers are shifting their focus from individual equipment performance toward complete production line integration and engineering execution capabilities. Leveraging extensive experience in advanced battery material equipment development, Boyee provides not only core manufacturing equipment but also complete engineering services covering: Process development, Laboratory validation, Pilot-scale scale-up, Automation and control integration, Production line integration, Turnkey EPC delivery.
Through this integrated approach, Boyee helps customers shorten development cycles, accelerate project implementation, and achieve a smooth transition from laboratory research to pilot validation and industrial-scale production.
Looking ahead, Boyee will continue focusing on: SWCNT production equipment, FCCVD continuous growth systems, SWCNT conductive slurry production lines, Integrated EPC solutions for conductive materials manufacturing. By continuously strengthening engineering capabilities and process innovation, Boyee aims to provide global customers with more stable, efficient, and intelligent manufacturing solutions for advanced conductive materials.
