Recent Advances in Carbon-Based Bifunctional Oxygen Catalysts for Zinc-Air Batteries

Journal Article


Abstract


  • Zinc-air batteries (ZABs) have recently received tremendous

    research attention due to their high theoretical energy

    densities. However, current ZABs suffer from poor energy

    efficiency and cyclability, mainly owing to the sluggish kinetics

    of the oxygen reduction reaction (ORR) and the oxygen

    evolution reaction (OER) on the air electrode. Therefore, rational

    design of efficient bifunctional oxygen electrocatalysts with

    high activity and stability is essential for improving battery

    performance. Carbon-based nanomaterials are promising candidates

    for bifunctional oxygen catalysis. In this review, we

    present the latest development of carbon-based bifunctional

    electrocatalysts for ZABs. Firstly, the related reaction mechanisms

    of bifunctional ORR/OER catalysts are introduced. Then,

    the recent advances in developing carbon-based bifunctional

    catalysts with tailored structure and promising catalytic performance

    are introduced following the regulation strategies,

    e. g., heteroatom doping, defect engineering, and/or hybridizing

    with other active materials. Finally, the key challenges and

    perspectives of advanced ZABs are provided to better shed

    light on future research.
