The effects of Li addition for the Bi-Sr-Ca-Cu-O ceramics on their superconductivities have been investigated. Bi-Sr-Ca-Cu-O superconducting ceramics with 2212 phase were successfully obtained at low temperatures below 800℃ by addition of LiF and Li_2CO_3 which acted as a flux. The obtained ceramics exhibited the superconducting transition with the T_c onset of 93K and the T_c end of 85K, which was detected by the electrical resistivity and magnetic susceptibility measurements. This high transition temperature, as compared with T_c=75K of Bi-Sr-Ca-Cu-O system with 2212 phase, was related to an increase of c-axis lattice constant by containing Li ions.
