Researchers develop deformable micro-supercapacitor via laser ablation patterning of Graphene/liquid metal
Researchers from Pohang University of Science and Technology (POSTECH), Korea Institute of Industrial Technology and Konkuk University have reported the development of a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling.

Micro supercapacitors (MSCs) have emerged as a promising candidate for deformable energy storage, due to high-power density, rapid charging, and long cycle life. However, the fabrication of interdigitated electrode patterns capable of maintaining the energy storage performance under repeated stretching and twisting has remained a great challenge, because brittle materials like gold (Au) have been commonly used as an electrode.
