Abstract: More efforts are needed to upgrade the performances of lithium-ion batteries (LIBs) for their further applications in various large electrical appliances such as electric vehicles and smart grid as these devices require high capacity, power density, high rate capability and especially safety. Electrode materials are the key to the performance of LIBs. Recently, metal oxides with much higher capacities and better safety have the prospect of becoming alternative anode materials of commercial graphite. However, the intrinsic low charge/ionic conductivity and poor cycling structural stability lead to poor cycling and rate performances, which greatly hinder their commercial applications. To overcome these disadvantages of metal oxide anodes for LIBs, several strategies have been developed during the past decade. Among them, metal oxide hollow micro-nanostructures exhibit excellent electrochemical properties as anode material for LIBs. In this review, we first describe the current commonly preparation methods to synthesize metal oxide hollow structures and comment on their advantages and shortages. According to some typical examples, we show the promising use of metal oxides hollow-structured anode materials for LIBs. Finally, the direction and prospect of metal oxide hollow micro-nanostructures using as anode materials are further discussed.
