    This research aspires to have an unconventional and alternative source for flexible and bendable energy storage devices, which has proved themselves very useful to meet the demand of today’s energy crises. It is very interesting to use natural self-growing plant’s lignocelluloses, which are very abundant on earth and convert them in the form of paper-based electrodes. In this research, Lignocelluloses were extracted from natural source Monochoria vaginalis (MV). Different samples were prepared for electrodes of energy storage applications like LC/PbO2/Au LC/PbO2/Ag, LC/PbO2/Ni by using single layer electrodeposition technique. Before using these samples as an electrode material for energy storage devices we characterized the samples for Electrodeposition, Scanning Electron Microscope, Cyclic Voltammetry and FTIR spectroscopy. Electrodeposition of Metallic layers are deposited on LC/PbO2 sheet by using three electrode setups. The SEM analysis displayed the fine fibril structure interlocked with each other displaying high mechanical properties with significant electrodeposited layers of Au, Ni and Ag. In these samples the nanoparticles of gold, silver and nickel are clearly visible with uniform electrodeposition. FTIR conforms the electrodeposition of gold, silver and nickel nanoparticles on LC/PbO2 sheet. CV is carried out for the LC/PbO2/Au, LC/PbO2/Ag and LC/PbO2/Ni samples displaying the amount of current increasing with increasing deposition time
