    This research aspires to have an unconventional and alternative source for flexible and bendable energy storage devices that has proved very useful to meet the demand of today’s energy crises. It is very interesting to use natural self-growing plant’s lignocellulose that are very abundant on earth and convert them in the form of paper-based electrodes. Fibers from papaya stem were taken and then dried, which were then treated in a solution to make flexible and smooth sheet. Addition of LC fiber makes the working electrode flexible, low cost and environmentally friendly for flexible energy storage applications. Tin sulphide (SnS) is a promising new material for use in several energy storage applications with a direct energy band gap of about 1.3 eV. Due to inherent rigid structure Tin sulfide cannot employ for modern flexible energy storage applications therefore, the composites of metal sulfides with the natural fibers will helpful to produce the flexible matrix for metal sulfides Poor conductivity of SnS/LC based flexible sheets were addresses by the electrodeposition of nanoparticles (i.e., MnS, Se-2) on fabricated sheets. The fabrication of Tin Sulfide based paper electrode results in boosting up the energy storage properties mainly its conductivity. Due to increment in energy storage properties, these electrodes have vast application in energy storage devices such as supercapacitors and sodium ion Batteries etc. These fabricated composites can be used further as flexible electrodes in energy storage applications because of enhanced electrochemical properties. Electrochemical cyclic voltammetry measurements were performed. CV results shows the at 100mvs materials with greater area under the curve has larger capacitance.
