Spinel-type transition metal oxide electrocatalysts for metal-air batteries

金属-空气电池具有高能量密度,是极具吸引力的电化学能量储存与转化器件,阴极反应动力学缓慢是制约其性能的关键因素之一,需要使用高效催化剂。本文简要介绍金属-空气电池的结构和工作原理,并综述近年来尖晶石型金属氧化物阴极催化剂的研究进展。

Metal air batteries are attractive devices for electrochemical energy storage and conversion because of high energy density. The slow kinetics of the cathodic electrochemical oxygen reduction/evolution is a key factor limiting the performance of metal air batteries, necessitating the use of active catalyst. In this review, we briefly introduce the structure and mechanism of prevailing metal-air batteries and summarize recent progress in applying spinel-type transition metal oxides as cathode catalysts to build metal-air battery.
