Rechargeable lithium–sulphur batteries could soon replace their lithium-ion equivalents in portable and wearable electronic gadgets. In addition to their low cost and small environmental footprint, they can store more energy per unit volume than conventional lithium batteries.

By creating foldable electrodes from composite thin films that combine tiny carbon nanotubes with highly porous metal–organic frameworks, Zhejiang University researchers have generated lithium–sulphur batteries with enhanced performance and extended lifespans. The tiny framework cavities boost conductivity by entrapping sulphur-containing species; the interwoven nanotubes provide flexibility and strength that preserve the electrode structure during volume changes as well as bending and folding.

By wirelessly connecting the body to state-of-the-art networks that continuously monitor and treat medical problems, these flexible batteries could form critical components of wearable electronics devices expected to revolutionize the health care industry.
