Micro‐Supercapacitors: 3D‐Printed Stretchable Micro‐Supercapacitor with Remarkable Areal Performance (Adv. Energy Mater. 14/2020)

In article number 1903794, Jiajie Liang and co-workers present a strategy for the 3D-printing and unidirectional freezing of a nanocomposite gel composed of MXene, MnO2 nanowires (NWs), AgNWs, and C60 to construct intrinsically stretchable micro-supercapacitors (MSCs) with thick and honeycomb-like porous interdigitated electrodes. The 3D-printed MSC exhibits high areal capacitance of 216.2 mF cm−2 at 10 mV s−1, and remains stable when stretched up to 50%.
