Article Synopsis
- A sustainable society needs advanced energy storage devices that are lightweight, compact, long-lasting, and safe, going beyond current battery and supercapacitor technologies.
- Single-walled carbon nanotubes (SWCNTs) show promise for this purpose, as they are tough and can be formed into ropes that store nanomechanical energy.
- These SWCNT ropes can store energy with a density of up to 2.1 MJ/kg, which is significantly higher than mechanical steel springs and three times more than advanced lithium-ion batteries, while also being stable and safe in extreme temperatures.
