摘要：

The electrochemical insertion of lithium into ceramic superconductor YBa2Cu3O7-δ was observed in potential range 3.15-2.15 V vs Li (in 1 M LiClO4/PC solution). The process is reversible. The estimated value of the diffusion coefficient, DLi = 10-12-10-11 cm2s-1, indicates a rather rigid bond between layers in the crystal lattice of the electrode material. The highest lithium concentration corresponds to the ratio Li: Y = 0.4-0.5. © 1990.
