Abstract

We report a simple approach to fabricate high performance energy storage devices based on aqueous inorganic ink comprised of hexagonal MnO2 nanosheets. The MnO2 ink exhibits long term stability. Continuous thin films can be formed on various substrates without using any binder. To obtain a flexible electrode for capacitive energy storage, we printed the MnO2 ink on commercially available A4 paper pre-treated by multi-walled carbon nanotubes. The electrode exhibited a maximum specific capacitance of 90.8 mF/cm2. The electrode could maintain 98.7% capacitance retention for 1,000 cycles at 10 mV/s. The MnO2 ink could be a potential candidate for large-scale production of flexible and printable electronic devices for energy storage and conversion. MRS Advances.
