Air electrodes including perovskites

A positive electrode may include an electrically conductive scaffold, conductive catalytic A-site deficient perovskite particles chemically bonded to the scaffold, an ion and gas permeable ionomer connecting the particles, and a hydrophobic porous layer on the scaffold. A secondary air electrode may...

More Information
Summary:A positive electrode may include an electrically conductive scaffold, conductive catalytic A-site deficient perovskite particles chemically bonded to the scaffold, an ion and gas permeable ionomer connecting the particles, and a hydrophobic porous layer on the scaffold. A secondary air electrode may include conductive bi-functional catalytic A-site deficient perovskite particles including AI-site lanthanum cations and AII-site alkaline earth metal cations, an ion and gas permeable ionomer connecting the particles, and a conductive scaffold in electrical contact with the particles.
