Layer-by-Layer Inkjet-Printed Manganese Oxide Nanosheets on Graphene for High-Performance Flexible Supercapacitors

Mohamed Ahmed Belal,

et al.

Abstract: The widespread adoption of wearable, movable, and implantable smart devices has sparked the evolution of flexible, miniaturized power supplies. High-resolution inkjet printing of flexible microsupercapacitor (μSC) electrodes is a fast, inexpensive, and wastefree alternative manufacturing technology. In this work, a 2D birnessitetype manganese dioxide (δ-MnO 2 ) water-based ink is used to print 10− 25 layers of δ-MnO 2 symmetrically on a preprinted interdigitated cell consisting of 10 layers of electrochemicall… Show more

“…36 This approach deviated from the conventional usage of inorganic supports like Al 2 O 3 , SiO 2 , and TiO 2 . 37–40 By leveraging the unique properties of MOFs, we were able to significantly enhance the process. Achieving improved metal dispersion within a carbon matrix, small particle size (averaged around 3 nm), and high metal loading after the pyrolysis of MIL-100(Fe) at low temperature.…”
