英文摘要	Ti-based materials are well-known to be good anode materials for lithium ion batteries because of their negligible volume change during the charge/discharge process. Nevertheless, poor electronic conductivity makes them exhibit relatively low capacity. Herein, we report our design of three-dimensional hierarchical Li4Ti5O12-TiO2/MoO2 nanoclusters embedded into carbon nanosheets core/shell porous superstructures for achieving more efficient lithium ion storage. The resulting hybrid makes full use of the advantage of high-capacity MoO2 nanoclusters and robust Li4Ti5O12-TiO2 substrate as well as high-conductivity carbon nanosheets. Such an assembly is highly particular for not only endowing enhanced ion diffusion and rapid electron transfer, but also preventing MoO2 nanoclusters from agglomeration and oxidation. Benefitting from the advantageous structural feature and synergistic effect of the components, the Li4Ti5O12-TiO2@MoO2/C exhibits a high reversible specific capacity of 413 mA g(-1) at a current density of 1000 mA g(-1) up to 500 cycles, indicating its high stability.; National Natural Science Foundation of China [51671003, 51472137]; National Basic Research Program of China [2016YFB0100201]; Peking University; Young Thousand Talented Program the China Postdoctoral Science Foundation [2017M610018]; SCI(E); ARTICLE; 24; 12096-12102; 5
