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.
