As the saying goes, the Stone Age did not end because we ran out of stones; we transitioned to better solutions. The same opportunity lies before us with energy efficiency and clean energy
The development of BBCP’s Nanobridge™ carbon nanotube (CNT) organo-metallic matrix conductor technology required overcoming a series of significant scientific challenges that have previously hindered advancements in conductivity, material strength, and reliability.
One of the primary difficulties was improving the conductivity of aluminum while maintaining its strength, ductility, and cost-effectiveness. While aluminum operates at only 60% of copper’s conductivity, it is lightweight and abundant, making it the primary conductor used in electricity transmission and applications such as lithium-ion batteries. For this reason, BBCP’s research team chose to focus on aluminum as a starting point. The goal to enhance aluminum’s electrical properties without compromising its mechanical characteristics necessitated several breakthroughs in nanotechnology and material engineering.
The journey to this breakthrough required cutting-edge research in material integration, surface chemistry, and nanotechnology, marking BBCP’s conductor as a foundational solution for next-generation electrical grids and clean energy systems.

Applications in our NanoBridge™ Ecosystem extend to electricity transmission, lithium-ion and Aluminum-ion batteries, busbars, connectors, wire harnesses, as well as generators, motors, and transformers (magnet wire).
Nanobridge™ combines the unique physical properties of carbon nanotube structures with advanced chemistry to overcome the challenges of electron transport at the metal-carbon interface. This innovative approach addresses key issues in conductivity and bonding, leveraging the strength and conductive efficiency of carbon nanotubes while ensuring seamless integration with the metal substrate. The result is a high-performance metallic matrix composite material optimized for efficient electron flow, setting a new standard in conductor technology.
The schematic diagram illustrates BBCP’s patented industrial process for producing the Nanobridge™ composite material. This process begins by preparing two sheets of a base metal substrate, onto which a specialized Nanobridge™ slurry is applied between the layers. The layers are then fed through high-pressure rollers, bonding the “sandwich” structure into a unified, single-stack spool. This initial spool can then be processed further to create multi-stack spools, where multiple bonded layers enhance the material’s conductivity and structural integrity.
Once the multi-stack spool is complete, it is ready for incorporation into various industrial processes, allowing for the development of an extensive range of materials tailored to different conductor applications, each benefiting from the enhanced performance characteristics of the Nanobridge™ composite.
