Carbon nanotubes have long been seen as an obscure, expensive and laboratory-bound material that is impossible to source in large quantities and notoriously shy about mingling with other materials (dispersion challenges). New manufacturing technologies have been developed that enable the production of carbon nanomaterials on a massive scale. Mass production and new methods for delivering these materials open the door to products that are affordable, safe to handle and easy to use. These developments are moving carbon nanotubes toward becoming an industrial commodity that will be used at scale for highly cost-sensitive applications such as cement additives and battery materials.
