While lithium-ion technology has long been the top choice for portable energy, there are now competing ideas that are more affordable and efficient, aiming to challenge its dominance. One such idea involves carbon nanotubes, a remarkable material stronger than steel that can store three times more energy per unit mass than lithium.
Researchers behind a recent study suggest that twisted single-walled carbon nanotubes could be ideal for medical devices, as they could harness energy from the body’s movements. Although the technology industry heavily relies on lithium-ion batteries for devices like smartphones, renewable energy storage, and electric vehicles, it is clear that an alternative is needed due to limitations of lithium-ion batteries, such as poor performance in extreme temperatures and environmental concerns associated with lithium extraction.
Various alternatives like iron-air batteries, proton batteries, and sodium batteries have been proposed, with carbon nanotubes emerging as a potential solution. A new international study revealed that ropes of twisted single-walled carbon nanotubes can store significantly more energy than steel springs and lithium batteries. These carbon nanotubes are also more durable in extreme temperatures and have been shown to be effective in various applications.
Although carbon nanotubes may not yet be suitable for powering everyday devices like smartphones, researchers believe they could revolutionize health implants by utilizing the body’s movements to generate energy for wearables and implants. The study’s co-lead author highlighted the potential of twisted carbon nanotubes for mechanical energy storage, drawing parallels to the historical use of coil springs for powering devices.”
