综述了层状双金属氢氧化物（LDH）的改性方法，通过将其自组装或者与电化学性能较好的材料复合使其成为一维、二维和三维结构，以进一步提高LDH的电化学性能，并介绍了各种结构的层状双金属氢氧化物在超级电容器中的应用。最后，对LDH未来改性的发展前景进行了展望。

The modification methods for layered double-metal hydroxides (LDHs) are reviewed.In order to improve the electrochemical performance of LDHs,LDHs with one-dimensional,two-dimensional and three-dimensional structures are respectively prepared through self-assembly or compounding LDHs with materials that have better electrochemical properties.The applications of LDHs with various structures in supercapacitors are also introduced.Finally,the development prospects of modified LDHs are expected.
