Since the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) in aprotic Li ion electrolytes are crucial reaction in the discharging and charging process of nonaqueous aprotic Li−air batteries, there is a strong demand for decreasing the overpotential by developing efficient catalysts for ORR and OER. In the present talk, I will introduce the recent results for the development of soluble catalyst based on quionoe derivatives and transition metal complexes with macrocyclic ligands, which are attractive in that the redox properties can be flexibly tuned by modifying the molecular structure and/or replacing the center metal ions.
