A mixture of tetrabutylammonium lithium phthalocyanine (TBA-LiPc) and dilithium phthalocyanine (Li2Pc) (2:1 mol ratio) functions as a bifunctional soluble hybrid catalyst in tetraethylene glycol dimethyl ether (TEGDME) for a rechargeable lithium-oxygen cell. Cyclic voltammetry (CV) measurements of the hybrid catalyst in TEGDME show highly symmetrical peaks at 2.54 V and 3.22 V vs Li/Li+ corresponding to oxygen reduction and oxygen oxidation reactions, respectively. Long-term cycling of cells with PVP-modified graphene nanosheets (GNSs) coated hierarchical porous carbons (HPC) cathodes at a fixed capacity of 1200 mAh/g (carbon) exhibits 402 and 379 cycles in oxygen and dry-air, respectively.
