Abstract
A cathode material used in an anode and a cathode contains (Co, Fe)3O4 and a perovskite type oxide that is expressed by the general formula ABO3 and includes at least one of La and Sr at the A site. A content ratio of (Co, Fe)3O4 in the cathode material is at least 0.23 wt % and no more than 8.6 wt %.
Claims4
A cathode material containing (Co, Fe)3O4 and a perovskite type oxide, the perovskite type oxide being expressed by the general formula ABO3 and including at least one of La and Sr at the A site, wherein:
- a content ratio of (Co, Fe)3O4 is at least 0.23 wt % and no more than 8.6 wt % with respect to a total weight of the cathode material, and
- a content ratio of the perovskite type oxide is 91.4 wt % or more with respect to the total weight of the cathode material.
