摘要：
The SnO2/Li4Ti5O12/C compound was gained via hydrothermal, sintering, and ball milling methods. Nano-grained SnO2/Li4Ti5O12 are homogeneously wrapped in a sheet-like graphite. Li4Ti5O12 possesses cyclic stability and superior rate capacity. Meanwhile, the SnO2/Li4Ti5O12 hybrid can supply abundant active sites for absorption of Li+, mitigate chemical stress in cycling, and prevent the ultrathin graphite nanosheets from stacking. Besides, the sheet-like graphite could reduce volume variation in cycling and reduce transmission distance for the electron or Li+. Therefore, an outstanding electrochemical property of the SnO2/Li4Ti5O12/C composite can be obtained.
