英文摘要：

The perovskite-type oxides with a formulation of ABO3 have recently been widely used as a new type of negative electrode materials for nickel-hydrogen （MH/Ni） secondary batteries due to their good activation performance, high discharge capacity and good chemical stability. This paper analyzes not only the challenges for the perovskite-type oxides used as negative electrode materials for MH/Ni batteries, but also the directions and recommendations for the future studies from three aspects including the synthesis,element doping and heterostructure compositing, which base on current study at home and abroad.
