| 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, people usually adopted the microstructure modification methods including doping, coating and nanosized the oxides. In this paper, the developing status of perovskite oxides hydrogen storage materials were summarized, 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 summarized and prospected. |
