|Abstract:||We prepared nano-sized tin (IV) oxide (SnO2) via molten-salt technique: heating a mixture of tin tetrachloride, lithium nitrate and lithium chloride at 280 °C in air. The powders are characterized by X-ray diffraction and transmission scanning microscopy techniques. The XRD studies showed a structure similar to tetragonal structure. The cyclic voltammetry studies showed characteristic cathodic peak potentials of reduction of Sn 4+ to Sn metal in the first cathodic scan, and alloying-de-alloying reaction of Sn at ∼0.25 and ∼0.5 V vs. Li for successive cathodic and anodic scans cycled in the voltage range, 0.005-1.0 V. Galvanostatic cycling studies show that reversible capacities (MSM SnO2 prepared at 280 °C) of 640, 720, 890 mAh g-1 in the voltage range, 0.005-1.0 V, 0.005-1.3 V and 0.005-1.5 V, respectively at a current rate of 100 mA g -1. We also discussed the effect of particle size and its electrochemical properties in the voltage range, 0.005-1.0 V. © 2013 Elsevier Ltd. All rights reserved.|
