Abstract

The spinel oxide Li_1+xTi₂O₄ with -0.3 ≤ x ≤ 1 has successfully been synthesized by the electrochemical Li intercalation/deintercalation technique. In the Li intercalation process, T _c ∼ 12 K is found to be almost independent of x, which is guessed to be due to the formation of a two-phase mixture of superconducting Li _1+xTi₂O₄ (x = 0-0.2) with T_c ∼ 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.
