Supercapacitors: Carbon‐Nanosheet Based Large‐Area Electrochemical Capacitor that is Flexible, Foldable, Twistable, and Stretchable (Small 43/2018)

In article number 1702145, In‐Suk Choi, Youngjin Jeong, Ji‐Hoon Lee, and co‐workers design a new type of mechanically robust electrochemical capacitor for wearable electronics based on all‐carbon‐based self‐supported nanocomposites. By optimizing the architecture of the three‐dimensional nanocomposite structure with activated carbons uniformly embedded in carbon nanotube sheets, outstanding durability and electrochemical performances are demonstrated under extreme mechanical deformations of bending, folding, twisting, and stretching.
