There are wide interests in developing high-performance electrode materials for electrochemical energy storage and conversion devices. Among them, transition metal nitrides (TMNs) are suitable for a wide range of devices because they have better electrical conductivity than the oxides and excellent catalytic properties. In particular, properly designed nanostructured TMNs offer additional advantages for performance enhancement. However, reviews of the rapid utilization of metal nitrides as electrode materials are still not much. In this mini-review, we present a recent (mostly since 2015) update on nanostructured TMNs as high-performance electrode materials for energy storage devices and water splitting; we discussed how a judicious nanostructure design will lead to improving performance in lithium ion battery, supercapacitor and Li-ion capacitor, as well as in electrochemical water splitting (oxygen and hydrogen evolution reactions). Knowledge about this review on metal nitrides is aimed at sharing a wide view in recent TMNs synthetic development, applications, prospects and challenges.

用于电化学储能和水分解的纳米结构过渡金属氮化物的开发进展

开发用于电化学能量存储和转换装置的高性能电极材料受到广泛关注。其中，过渡金属氮化物（TMNs）由于具有比氧化物更好的导电性和优异的催化性能而适用于广泛的器件。特别是，适当设计的纳米结构 TMN 为性能增强提供了额外的优势。然而，关于金属氮化物作为电极材料的快速利用的评论仍然不多。在这篇小型评论中，我们介绍了最近（主要是自 2015 年以来）关于纳米结构 TMN 作为用于储能设备和水分解的高性能电极材料的更新；我们讨论了明智的纳米结构设计将如何提高锂离子电池、超级电容器和锂离子电容器的性能，以及电化学水分解（析氧和析氢反应）。关于金属氮化物的这篇综述的知识旨在分享最近 TMN 合成发展、应用、前景和挑战的广泛观点。
