Abstract

NiMn₂O₄ with different crystal structures was successfully synthesized and evaluated as a cathode catalyst for rechargeable Li–air batteries for the first time. The result reveals that the intermediate spinel structure between normal and inverse spinels demonstrates faster kinetics towards ORR/OER than the normal spinel, leading to a better battery performance.
