Abstract
The structural evolution of SnO2 fine powder prepared by a sol-gel met hod upon heat-treatment was investigated by using x-ray diffraction. E lectrochemical measurements showed that the reversible capacity of lit hium ion reaction with the SnO2 electrode could be as high as 600 mAh/ g. The mechanism of lithium ion reaction was studied by ex situ x-ray diffraction and Raman spectroscopy. Two processes were revealed: a sub stitution reaction, in which SnO2 is reduced and Sn is formed, followe d by LiySn alloy formation.
