An international team of scientists has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.
An international team of scientists, including two researchers who now work in the Center for Advanced Sensor Technology at UMBC, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.
To investigate carbon nanotubes' potential for storing energy, the UMBC researchers and their colleagues manufactured carbon nanotube"ropes" from bundles of commercially available nanotubes. After pulling and twisting the tubes into a single thread, the researchers then coated them with different substances intended to increase the ropes' strength and flexibility.
"Humans have long stored energy in mechanical coil springs to power devices such as watches and toys," Kumar Ujjain says."This research shows twisted carbon nanotubes have great potential for mechanical energy storage, and we are excited to share the news with the world." He says the CAST team is already working to incorporate twisted carbon nanotubes as an energy source for a prototype sensor they are developing.
Today, most rechargeable batteries are lithium-ion batteries, which are made from relatively scarce elements--this calls for the development of batteries using alternative materials. In a new study, ...
