Zusammenfassung:	<jats:title>Abstract</jats:title><jats:p> Tin oxide (SnO<jats:sub>2</jats:sub>) nanostructures and SnO<jats:sub>2</jats:sub>/Polyaniline (PANI) nanocomposites to be used as electrode materials for a lithium ion battery were synthesized using a solution-route technique with chelating agents followed by calcination at 300∘C for 4 h. Structural and morphological properties were studied with powder X-ray diffraction, scanning electron and transmission electron microscopy. Particles of 25-10 nm size are observed in the microscope images. TGA results showed that the PANI-modified SnO<jats:sub>2</jats:sub> nanoparticles exhibit higher thermal stability than the SnO<jats:sub>2</jats:sub> nanoparticles. Electrochemical properties of SnO<jats:sub>2</jats:sub> and SnO<jats:sub>2</jats:sub>/PANI electrodes were examined in a lithium ion battery and a supercapacitor. The electrode of SnO<jats:sub>2</jats:sub>/PANI shows higher specific capacity. The cell with SnO<jats:sub>2</jats:sub>/PANI exhibits a specific capacity of 1450 mAh/g at C/10. Supercapacitor results indicate that the PANI-modified SnO<jats:sub>2</jats:sub> composite had a higher current with apparent cathodic and anodic peaks.</jats:p>
