Summary: | SnO
2
nanorods were synthesized via a simple, facile, and cost-effective co-precipitation route using sodium dodecyl sulfate (SDS) as a surfactant. The structural, morphological, and electrochemical properties of the prepared SnO
2
nanorods were investigated. Morphological analysis revealed the formation of rods due to the presence of anionic surfactant. Electrochemical analysis of the electrodes in an alkaline electrolyte revealed the pseudocapacitive behavior of the nanorods of SnO
2
. The tin oxide nanorods were capable of delivering maximum specific capacitance of 108 F g
−1
at a specific current of 2 A g
−1
. Moreover, an asymmetric supercapacitor was fabricated utilizing SnO
2
and activated carbon (AC) as electrodes. The fabricated two-electrode cell has remarkable power density of 1234 W kg
−1
. From these measurements, it can be concluded that SnO
2
appears to be a promising pseudocapacitor material.
