A Korean research team has developed a lithium-ion
battery that is flexible enough to be stretched. Dr. Jeong Gon
Son’s research team at the Photo-Electronic Hybrids Research Center
at the Korea Institute of Science and Technology (KIST) announced
that they had constructed a high-capacity, stretchable lithium-ion
battery. The battery was developed by fabricating a structurally
stretchable electrode consisting solely of electrode materials and
then assembling with a stretchable gel electrolyte and stretchable
packaging.
