Abstract
The deformable electronic devices such as flexible, foldable, bendable, wearable, etc., are deemed the future of portable electronics, which could only be realized through the proper design of an energy storage unit that could power them. Herein, we report the conception of an ultrastable, binderless flexible electrode/substrate configuration that can be implemented in various energy storage applications such as supercapacitors, lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, and alike. Firstly, the conductive carbon fabric was electrochemically deposited with nickel nanospheres; then the ZIF-67 metal-organic framework (MOF) promoted metal hydroxide nanostructures were grown over the Ni-CCF substrate. As grown nanostructures were then embedded inside the CCF through a meticulous optimization process varying the calcination temperature and gas concentrations. The metal seed embedded CCF was then coated with the hydrocarbons, the precursors of which are generally known volatile organic compounds and pollutants such as C2H4, CH4, CO2, and NH3 through the dielectric barrier discharge (DBD) plasma at atmospheric pressure and temperature. The carbonization of the final product results in the ultra-robust flexible electrode with metal-oxide nano seeds embedded CCF, coated with ~20nm nitrogen-doped carbon thin film which will be an excellent electrode material for an ultra-long life flexible energy storage system.
