Abstract
Scandium and Niobium doped Lithium Titanate is prepared by a sol-gel technique based on the formula Li4-x ScxTi5-y NbyO12, where x = y = 0.0 & 0.3 i.e. Li4 Ti5 O12 and Li3.7 Sc0.3 Ti4.7 Nb0.3 O12. The specific capacity of Sc and Nb incorporated LTO has been observed as 227.5 mAhg-1 at 1 c, while this value has shown a decrease in the value of the specific capacity of the electrode i.e. 105.5 mAhg-1 at 20 c even after many test cycles. It has also been observed that Sc-Nb doping is suitable for the reversible cycle of the battery system and the extraction of Li+. [ABSTRACT FROM AUTHOR]
