Abstract

Solid-state Li_1+xAl_xGe_2-x(PO₄)₃ electrolytes with high ionic conductivity were prepared and successfully applied in lithium-oxygen batteries (LOBs). Combined with MOF-derived NiCo₂O₄ cathodes, the solid-state LOBs deliver a high discharge capacity and good rate performance. Moreover, enabled by such a bifunctional cathode, the as-assembled solid-state LOBs show enhanced reversibility and long-term cycling stability over 90 cycles.
