可充锌空气电池非贵金属阴极催化剂研究进展

Research progress on non-precious metal cathode catalysts for rechargeable zinc-air battery

针对不同催化剂体系下可充锌空气电池的研究情况和发展问题进行了综述。可充锌空气电池的氧还原反应(ORR)和氧析出反应(OER)速度缓慢,限制了它们的大规模应用。目前对可充锌空气电池的研究主要集中在非贵金属阴极催化剂上,以杂原子掺杂碳材料、过渡金属氧化物以及过渡金属硫化物为代表。最后对非贵金属阴极催化剂研究提出了展望。

This review focuses on the research situation and development problems of rechargeable zinc-air batteries under different catalyst systems.Rechargeable zinc-air batteries have low oxygen reduction(ORR)and oxygen evolution(OER)reaction speeds,which limiting their wide application.At present,the research on rechargeable zinc-air batteries is mainly focused on non-precious metal cathode catalysts,including heteroatom doped carbon materials,transition metal oxides and transition metal sulfides.Finally,prospects for non-precious metal cathode catalyst research are put forward.
