Abstract
There have been few studies on tin selenide (SnSe) as a supercapacitor electrode. In this paper, SnSe nanorods
were obtained via a simple, solvothermal, one-step method, then its modification by reduced graphene oxide
(rGO) was studied. SnSe/rGO composites with different rGO ratios were prepared and the electrochemical
measurements showed that the best electrochemical performance among them was SnSe/7rGO which showed
a good electrochemical efficiency exhibiting a capacitance of 568 F g−1 at 1 A g−1. A hybrid supercapacitor
device was prepared using SnSe/7rGO as a positive electrode and activated carbon as a negative electrode
to further investigate the electrochemical efficiency of this material. The produced device exhibited a specific
energy of 30.5 Wh kg−1 at a specific power of 1.007 kW kg−1 and still maintained 4 Wh kg−1 at a power density
of 1.24 kW kg−1. The obtained results suggesting that the as-synthesized electrode has great potential in
applications of supercapacitors.
