Scientists in South Korea have developed stretchable aqueous lithium-ion batteries that may power the next generation of wearable devices.
Using hybrid carbon/polymer (HCP) composite as a stretchable current collector, the research team developed a highly stretchable rechargeable battery based on aqueous electrolytes, according to the study published in the journal Advanced Energy Materials.
Stretchable electronic devices have recently attracted tremendous attention as next-generation devices due to their immense flexibility.
The increasing interest and demand of flexible electronics has fuelled the search for highly stretchable electrodes with high mechanical durability and high electrical conductivity during deformation.
Although many methods have been proposed for these electrodes, none of them has managed to simultaneously achieve high stretchability for the electrodes and have a scalable manufacturing process.
The research led by professor Soojin Park of UNIST solved such issues using a conductive polymer composite, composed of Jabuticaba-like hybrid carbon fillers containing carbon nanotubes and carbon black in a simple solution process.
