LaCoO3 – δ as the Material of an Oxygen Electrode for a Molten Carbonate Fuel Cell: I. Electrophysical Properties of Lithiated LaCoO3 – δ
Oxides LaCoO 3 – δ + ( z /2) Li 2 O (0 ≤ z ≤ 0.15) are synthesized to determine the boundaries of changing the electrophysical properties of LaCoO 3 – δ due to its in situ lithiation in the (Li 0.62 K 0.38 ) 2 CO 3 eutectic melt. A perovskite-like solid solution (La 1 – x Li x )(Li x Co 1 – x )O 3 –...
