摘　　要：镍氢电池具有循环寿命长、安全性高等优点而被广泛应用于医疗设备、军事设施以及混合动力汽车等领域。镍氢电池性能的优劣主要取决于作为负极的储氢材料。目前已开发的众多储氢材料中,钙钛矿型氧化物材料具有循环寿命长、价格低廉、高温下储氢性能优良等优点,成为一类极具应用前景的新型储氢材料。为进一步提高其储氢性能,人们通常采取掺杂、包覆及将材料进行纳米化等方法对其进行微观结构修饰。本文对钙钛矿氧化物储氢材料发展现状进行了概述,系统介绍了钙钛矿型氧化物负极材料的储氢机理,重点详细阐述了对钙钛矿型氧化物进行A位掺杂、B位掺杂、AB共掺杂、包覆处理和抑制剂处理等不同微观结构修饰技术对其电化学储氢性能的影响,同时对钙钛矿型氧化物负极材料的未来发展前景进行了总结及展望。Nickel-metal hydride batteries have been widely used in medical equipment,military facilities,and hybrid vehicles due to their unique advantages such as excellent cycle life and high safety.In general,the performance of nickel-metal hydride battery depends on the hydrogen storage material used as the negative electrode.Among the various negative hydrogen storage materials that have been developed,perovskite oxide materials have the advantages of long cycle life,low price and excellent hydrogen storage performance at high temperature,and have become a new type of electrode materials with great application prospect.In order to further improve the hydrogen storage performances of the oxides,the microstructure modification methods including doping,coating and nanosized the oxides were usually adopted.In this paper,the developing status of perovskite oxides hydrogen storage materials were reviewed,the hydrogen storage mechanism of perovskite oxides was introduced systematically.The effects of different microstructure modifications such as A-site doping,B-site doping,AB co-doping,coating treatment and inhibitor treatment on the electrochemical hydrogen storage performance of perovskite oxides were discussed in detail,and the prospects for future research of perovskite oxides were prospected.
