Influence of supporting electrolytes on the structure of electrodeposited SnO2 thin films for energy storage applications

Influence of supporting electrolytes on the structure of electrodeposited SnO2 thin films for... Different SnO2 nanostructures (SnO2Ns) were directly electrodeposited on the surface of anodized copper (Cu) substrates via the potentiostatic electrodeposition method with addition of supporting electrolytes. The effects of the supporting electrolytes and the electrodeposition parameters on the evolution of nanostructures and on the electrochemical properties of the SnO2Ns were systematically investigated using field emission scanning electron microscope (FESEM) and electrochemical methods including cyclic voltammetry (CV) and chronoamperometry (CA). The results confirmed that SnO2Ns exhibit alloying/de-alloying reactions with Li+ ions versus Ag/AgCl in aqueous electrolyte solution (LiOH·H2O and Li2CO3). The super capacitor performance of the SnO2Ns was investigated in 0.5-M Na2SO4 aqueous solution, and the highest specific capacitance of 110 Fg−1 at a scan rate of 5 mV s−1 was obtained for SnO2 microspheres made up of nanocubes.

Abstract

Different SnO2 nanostructures (SnO2Ns) were directly electrodeposited on the surface of anodized copper (Cu) substrates via the potentiostatic electrodeposition method with addition of supporting electrolytes. The effects of the supporting electrolytes and the electrodeposition parameters on the evolution of nanostructures and on the electrochemical properties of the SnO2Ns were systematically investigated using field emission scanning electron microscope (FESEM) and electrochemical methods including cyclic voltammetry (CV) and chronoamperometry (CA). The results confirmed that SnO2Ns exhibit alloying/de-alloying reactions with Li+ ions versus Ag/AgCl in aqueous electrolyte solution (LiOH·H2O and Li2CO3). The super capacitor performance of the SnO2Ns was investigated in 0.5-M Na2SO4 aqueous solution, and the highest specific capacitance of 110 Fg−1 at a scan rate of 5 mV s−1 was obtained for SnO2 microspheres made up of nanocubes. Our study shows that supporting electrolytes and electrodeposition parameters play the significant role in the growth of SnO2Ns and its electrochemical properties.
