摘要：

The spinel oxide Li1+xTi2O4 with -0.3 <= x <= 1 has successfully been synthesized by the electrochemical Li intercalation/deintercalation technique. In the Li intercalation process, T-c similar to 12K is found to be almost independent of x, which is guessed to be due to the formation of a two-phase mixture of superconducting Li1+xTi2O4 (x = 0-0.2) with T-c similar to 12 K and nonsuperconducting Li2Ti2O4. In the Li deintercalation process, on the other hand, T-c is found to slightly increase up to 13.3 K. (C) 2009 Elsevier B.V. All rights reserved.
