Flexible Li‐doped Bi‐Sr‐Ca‐Cu‐O superconducting whiskers have been prepared by heating a glassy melt‐quenched plate in a stream of O2gas. The whiskers show a resistance drop at 110 K with a zero resistance at 81 K. These values are higher than those of the Pb‐doped Bi‐Sr‐Ca‐Cu‐O whiskers by 5 and 11 K, respectively. The doping of Li is effective to raiseTcfor both the 2212 phase and the 2223 phase. TheJcvalues of the Li‐doped whiskers are 30 000 A/cm2at 77 K and 300 000 A/cm2at 66 K in a zero magnetic field.
