Popis: | Effective conductivities of porous electrodes containing FeS as the initial active material and 54 weight percent (w/o) LiCl-KCl electrolyte were experimentally determined at 450/sup 0/C for different states of charge by means of an a-c impedance bridge. The effective conductivity of the fully charged FeS electrode was found to be approximatel 7 ..cap omega../sup -1/ X cm/sup -1/, about four times higher than the conductivity of the electrolyte. This high effective conductivity is considered to be one of the superior features of the FeS cells because such high conductivity results in high power density without the addition of conductive material. The change of the electrode effective resistance during the discharge is discussed in connection with both the electrode reactions and the results of metallographic examinations. |
