摘　　要：High capacity Fe_(3)O_(4)-based anode materials have attracted a great deal of attention as an alternative to commercial graphite in Li-ion batteries(LIBs).However,it is still a challenge to alleviate the fast capacity fading of Fe_(3)O_(4) due to the intercalation of Lit.In this work,we develop a novel and effective strategy to rapidly fabricate the hollow Fe_(3)O_(4) nanostructures via the solvent-induced effect.The influence of the ratio of the tert-butanol(TB)and the water on the microstructure was further discussed.As expected,when the hollow nanostructures based on the 1:1 ratio of TB and water is used as the anode material for LIBs,a high reversible capacity of 1020 mA h g^(-1) after 100 cycles at 1 A g^(-1) and 450 mA h g^(-1) even for 5 A g^(-1) after 1000 cycles can be obtained,paving a new avenue to fabricate the functionally hollow nanostructures for high-performance anode materials or other applications.
