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 Bi<SUB>2</SUB>Sr<SUB>1.5</SUB>Ca<SUB>1.5</SUB>Cu<SUB>2</SUB>O<SUB>z</SUB> 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, Li<SUB>x</SUB>Bi<SUB>2</SUB>Sr<SUB>1.5</SUB>Ca<SUB>1.5</SUB>Cu<SUB>2</SUB>O<SUB>z</SUB>, 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.
