ABSTRACT:
A positive electrode for galvanic high-temperature cells with solid negative electrodes based upon Li, Mg, Ca or Al is produced by sintering a heavy metal sulfide (e.g. FeS, CnS), with a heavy metal powder (e.g. Fe, Ni). In the sinter electrode the heavy metal powder present in weight percentage of about 20% to 40% forms a rigid electrically conductive framework in which the active heavy metal sulfide is embedded. The free-pore volume of the electrode is about 50%.
