Fabrication and Characterization of Tin Oxide Based Flexible Composites for Energy Storage Applications

Abstract

Tin Oxide (SnO2) is excessively used for energy storage applications due to wide potential, transparency and thermal stability. Several methods are reported for fabrication of SnO2 nano structures e.g. electro spinning, chemical vapor deposition process, self assembly, homogeneous precipitation method, thermal decomposition and hydrothermal method. Hydrothermal method is advantageous due to low cost, template free, environment friendly and low temperature. In this study, SnO2 is fabricated via hydrothermal method and furthermore composites with CuO, ZnO and lignocelluloses fiber are synthesized for development of electrochemically efficient and flexible paper electrodes for energy storage. X-Ray diffraction, Scanning Electron Microscopy (SEM), FTIR and Cyclic Voltammetry measurements of fabricated composites were employed to characterize the morphology, structural and electrochemical characteristics. SEM reveals the nano-petal and nanorods morphology of SnO2 and CuO, respectively. XRD measurements confirm the fabrication of SnO2, SnO2/CuO and ZnSnO3 by JCD cards (41-1445), (48-1548) and (34-1451) respectively. Cyclic Voltammetry confirm the electrochemical kinetics of fabricated composites which are highly feasible for super capacitors and batteries.
