Abstract
The effects of electrochemical removal reaction of lithium from the Li-doped Bi-2212 phase on its structure and superconducting properties have been studied. Lithium was inserted into and removed from Bi2Sr1.5,Ca1.5Cu2Oz through an electrochemical method at a constant applied potential at room temperature. The original crystal symmetry, tetragonal structure, was maintained and any secondary phase was not formed throughout the electrochemical reactions. Lattice parameter c of the doped samples, LixBi2Sr1.5Ca1.5Cu2O z, decreased and Tc changed reversibly as the lithium content x decreased. It reveals that the electrochemical reactions were intercalation/deintercalation of the Bi-2212 phase with lithium.
