    Due to increase in demand for energy storage in today’s society, the development of inexpensive, flexible and light weight energy storage device is essential. In this respect, paper-based energy storage devices are highly being preferred. In this work, we report the fabrication and performance of super capacitors made from carbonized peanut shells and sugarcane which are renewable materials with a huge annual yield and are usually discarded directly by people. With proper treatment, peanut shells could be used for many applications. The aim of this thesis to evaluate the use of peanut shell flour and crushed wasted sugarcane cellulose fibers and conductive polymers i.e. polyaniline and polypyrene are used for paper-based energy storage devices. Two conductive composite paper materials were developed by covering the individual lignocelluloses fibers obtained from the peanut shells and sugarcane plant with a conducting polymer (Polyaniline, polypyrrole) coating.
