Scientists from various Russian universities and research centers have developed a new method for attaching carbon nanotubes to a titanium substrate. This approach makes it possible to create new materials for supercapacitor electrodes without using polymer binders.
Single-walled carbon nanotubes are microscopic structures consisting of a single layer of carbon. They have high conductivity, durability and stability. Multi-walled nanotubes, on the other hand, consist of several layers and are used in various fields, for example, to strengthen materials in mechanical engineering and to create efficient devices in microelectronics.
Scientists have long been investigating the use of nanotubes as electrode materials for supercapacitors. They believe that multi-walled nanotubes are more promising because they have a variety of shapes and configurations compared to single-walled ones. A new method of attaching nanotubes to a titanium substrate improves surface adhesion, making it useful not only for creating supercapacitors but also for lithium-ion batteries.
