Progress in the application of Fe-based metal oxide/hydroxide as kathode materials in supercapacitor
【摘要】 纳米结构铁基金属氧化物/氢氧化物(如Fe2O3,Fe3O4及FeOOH等),因具有较高的理论比电容和较宽的负向电位窗口,被认为是一种潜在的理想超级电容器负极材料,但Fe基电极大多数具有较差的导电性及不稳定的电化学性能,使其实际应用受到阻碍.为此,科研人员为提高其导电性及电化学稳定性做了大量的工作.该文概述提高Fe基纳米结构负极材料导电性和电化学稳定性的有效方法,介绍Fe基纳米结构负极材料在纳米结构设计和合成方面的最新研究进展,展望其未来的应用前景.
【Abstract】 Nanostructured Fe-based metal oxides/hydroxides such as Fe2O3, Fe3O4, FeOOH have high theoretical specific capacitance and wide negative potential working window, but they have several drawbacks such as poor conductivity, structural instability during charge-discharge processes, which seriously hinders their practical application. Therefore, researchers have done a lot of work to improve their electrical conductivity and electrochemical stability. In this paper, the effective methods for improving the conductivity and electrochemical stability of Fe-based nanostructured kathode materials were reviewed. The latest research progress of Fe-based nanostructured kathode materials in nanostructure design and synthesis was introduced, and its future application prospects were expected.
