The relentless pursuit of new electrode materials for lithium ion batteries (LIBs) has been conducted for decades. Structures with either porous or nanostructure configurations have been confirmed as advantageous candidates for energy storage/conversion applications. The integration of the two features into one structure can provide another chance to improve the electroactivities. Recently, single-phased mixed metal oxides (MMOs) containing different metal cations, in particular, have confirmed high electrochemical activities because of their complex chemical composition, interfacial effects, and the synergic effects of the multiple metal species. In this review, we will focus on recent research advances of MMOs with porous architectures as anode materials in the matter of structural arrangement and compositional manipulation. Moreover, the application of self-supported MMO-based porous structures as LIB anodes is also explained herein. More importantly, investigations on the synthetic system and formation mechanism of porous MMOs will be highlighted. Some future trends for the innovative design of new electrode materials are also discussed in this review. The challenges and prospects will draw many researchers' attention.
数十年来，人们一直在不懈地追求用于锂离子电池（LIBs）的新型电极材料。具有多孔或纳米结构构型的材料已被确认为储能/转换应用的优势候选材料。将这两种特性整合到一种结构中可以提供另一个改善电活性的机会。最近，特别是含有不同金属阳离子的单相混合金属氧化物（MMOs），由于其复杂的化学成分、界面效应和多种金属物种的协同效应，已被证实具有高电化学活性。在这篇综述中，我们将重点关注具有多孔结构的MMOs作为阳极材料在结构排列和成分调控方面的最新研究进展。此外，本文还解释了自支撑的基于MMO的多孔结构作为LIB阳极的应用。更重要的是，将突出对多孔MMOs的合成体系和形成机制的研究。本综述还讨论了新型电极材料创新设计的一些未来趋势。这些挑战和前景将吸引许多研究人员的关注。
