C. Natarajan et al., PREPARATION OF A NANOCRYSTALLINE TITANIUM-DIOXIDE NEGATIVE ELECTRODE FOR THE RECHARGEABLE LITHIUM ION BATTERY, Electrochimica acta, 43(21-22), 1998, pp. 3371-3374
Titanium dioxide powders with different crystalline forms were prepare
d from a simple aqueous peroxo route. Amorphous, nanocrystalline and c
rystalline TiO2 phases were obtained by heat-treating the precursor, T
i-peroxo complex, at different temperatures. The TiO2 powders were cha
racterized by physical and electrochemical methods in a 1 M LiClO4/pro
pylene carbonate solution for the anode in a lithium ion battery. A ma
ximum reversible discharge capacity of 140 mA h g(-1) was observed for
the nano-crystalline titanium dioxide. The effect of heat-treatment t
emperature on the crystallinity and consequently on the storage capaci
ty of TiO2 has been briefly discussed. (C) 1998 Elsevier Science Ltd.
