A new single molecular precursor route to fluorine-doped nanocrystalline tin oxide anodes for lithium batteries

A fluorine-doped nanocrystalline tin oxide has been prepared by thermolysis of xerosol derived from a single molecular precursor. A fluorine to tin at omic ratio, as high as 0.14, was estimated from the results of elemental an alysis. The oxidation state of Sn and conducting properties were determined by Mossbauer spectroscopy and resistivity measurements. According to the e lectrochemical experiments, a reversible capacity up to similar to 800 mAh/ g has been achieved. (C) 2001 Elsevier Science Ltd. All rights reserved.
