Green Precursors and Soft Templating for Printing Porous Carbon‐Based Micro‐supercapacitors

Abstract A combination of soft lithographic printing and soft templating has been used to fabricate high‐resolution interdigitated micro‐supercapacitors (MSC). Surfactant‐assisted self‐assembly produces high surface area ordered mesoporous carbons (490 m 2 g −1 ). For the first time, such precursors have been printed by nano‐imprint lithography as microdevices with a line width of only 250 nm and a spacing of only 1 μm. The devices are crack‐free with low specific resistance (1.2×10 −5 Ωm) and show good device capacitance up to 0.21 F cm −3 .
