Electrochemical characteristics, thermal and chemical compatibility in the La0.7Sr0.3CoO3 electrode-γ-BIFEVOX electrolyte system

The electrochemical characteristics and compatibility of components of the electrode-electrolyte system, where the electrolyte is chosen to be γ-BIFEVOX compositions crystallizing in a stable tetragonal phase and the cathode material is chosen to be composite electrodes of composition La0.7Sr0.3CoO3 + Bi4V1.7Fe0.3O11 − δ, were studied.
