Abstract

The effects of electrochemical Li-doping on superconducting properties of the Bi-2212 phase have been investigated. The electrochemical Li-doping into the 2212 phase was first succeed with remaining the original crystal structure and without formation of any second phase. Maximum Li content y as LiyBi2Sr1.5Ca1.5Cu2O z by this electrochemical reaction was found to be 0.37. The Li content increased with increasing in reaction time and applied potential. The lattice parameters (a, c) of the Bi-2212 crystals increased continuously from (5.397Å, 30.69Å) for y=0.0 to (5.411Å, 30.89Å) for y=0.37. Tc of the doped samples continuously decreased to 0K for around y=0.27.
