英文摘要	Searching the long-life transition-metal oxide (TMO)-based materials for future lithium-ion batteries (LIBs) is still a great challenge because of the mechanical strain resulting from volume change of TMO anodes during the lithiation/delithiation process. To well address this challenging issue, we demonstrate a controlled method for making the multishelled TMO hollow microfibers with tunable shell numbers to achieve the optimal void for efficient lithium-ion storage. Such a particularly designed void can lead to a short diffusion distance for fast diffusion of Li+ ions and also withstand a large volume variation upon cycling, both of which are the key for high-performance LIBs. Triple-shelled TMO hollow microfibers are a quite stable anode material for LIBs with high reversible capacities (NiO: 698.1 mA h g(-1) at 1 A g(-1); Co3O4: 940.2 mA h g(-1) at 1 A g(-1); Fe2O3: 997.8 mA h g(-1) at 1 A g(-1)), excellent rate capability, and stability. The present work opens a way for rational design of the void of multiple shells in achieving the stable lithium-ion storage through the biomass conversion strategy.; National Natural Science Foundation of China [51473081, 51672143, 51671003]; National Basic Research Program of China [2016YFB0100201]; Peking University and Young Thousand Talented Program; SCI(E); ARTICLE; 6; 6186-6193; 11
