 Hierarchically nanostructured transition metal oxide, TMO, materials have recently emerged as promising candidates for lithium-ion battery, LIB, applications due to their unique structural features and enhanced electrochemical properties. This review provides an overview of the synthetic strategies, morphology, and electrochemical performance of these materials. The advantages of hierarchical structures such as increased surface area, faster ion transport, and improved cycle stability are highlighted. Furthermore, some potential future directions are suggested. This article was authored by Mingbo Zheng, Hao Tang, Lu Lu Li, and others.
