英文摘要	Searching for high-performance anode materials to alleviate the low capacity issue of commercial graphite is advantageous for the future development of lithium-ion batteries (LIBs). In this work, an oxygen vacancy-enriched zinc manganate anchored on a reduced oxide graphene (O-ZMO/rGO) nanocomposite was synthesized and used as an anode material in LIBs. As expected, the O-ZMO/rGO electrode delivers a high specific capacity of 1272.1 mA h g(-1) after 100 cycles at a current density of 0.2 A g(-1), an excellent rate capability, and long-term cycling stability of up to 700 cycles with 780.0 and 432.7 mA h g(-1) capacity retained at high current densities of 1.0 and 2.0 A g(-1), respectively. Oxygen vacancies provide abundant active sites and the small particle size of 10-20 nm shortens the diffusion distance of the Li+ ions and transfer path of the electrons, while rGO enhance the electrical conductivity, thus contributing to the excellent lithium storage performance. Also, capacitance-controlled behavior was found to dominate the lithium ion transport kinetics during the electrochemical reaction process.
