Efficiency of 3D-Ordered Macroporous La_0.6Sr_0.4Co_0.2Fe_0.8O₃ as an Electrocatalyst for Aprotic Li-O₂ Batteries.

ABSTRACT: Li-O₂ batteries (LOBs) with an extremely high theoretical energy density have been reported to be the most promising candidates for future electric storage systems. Porous catalysts can be beneficial for LOBs. Herein, 3D-ordered macroporous La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite oxides (3D-LSCF) are applied as cathode catalysts in LOBs. With a high Brunauer-Emmett-Teller surface area (21.8 m² g^-1) and unique honeycomb-like macroporous structure, the 3D-LSCF catalysts possess a much higher efficiency than La_0.6Sr_0.4Co_0.2Fe_0.8O₃ (LSCF) nanoparticles. The unique 3D-ordered macropores play a significant role in the product deposition as well as oxygen and el
