These requirements mainly demand technology that enables power retention and energy density under various mechanical deformation conditions.
These great qualities come from the fiber’s tightly packed and aligned structure and the fact that it’s made of highly crystalline carbon nanotubes with few defects. However, this method has drawbacks. The added materials might come off during use, and the process is unsuitable for making long, continuous fibers. Researchers highlight the need for a new way to improve CNTFs for energy storage without adding extra materials, making it cheaper and more practical.As a solution, the KIST team developed special carbon nanotube fibers that can store energy well without needing extra steps or materials.
