Exfoliated Graphite Nanosheets Coating on Nano-grained SnO/LiTiO as a High-Performance Anode Material for Lithium-Ion Batteries.

The SnO/LiTiO/C compound was gained via hydrothermal, sintering, and ball milling methods. Nano-grained SnO/LiTiO are homogeneously wrapped in a sheet-like graphite. LiTiO possesses cyclic stability and superior rate capacity. Meanwhile, the SnO/LiTiO 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 SnO/LiTiO/C composite can be obtained.
