초록

An oxide, Li1.1Nb0.9O2 - x, is proposed as a novel active material for the negative electrode of lithium secondary batteries. The material was selected by first principles calculation and its real properties as a negative electrode were measured after it is synthesized by solid state reactions. Lithium ions are inserted into the material at potentials <0.3 V vs. Li/Li+. Its reversible capacity is similar to 120 mAh g(-1) after 50 cycles. (C) 2012 Elsevier B.V. All rights reserved.
