For the nano-Li hybrid preparation, the raw Li and 3% glucose were firstly ultrafine ball milled for 1.5 h, and then 3% graphitized CNTs (Chengdu Organic Chemicals Co. Lid., Chinese Academy of Sciences) were added into the slurry. Then the mixed slurry was milled for another 2 h at 300 r/min to uniformly disperse the CNTs. Finally, the slurry was spray dried and sintered at 600 C in Ar/H for 6 h to yield the resultant nano-Li/c/cnt hybrid, the overall carbon content of this hybrid materialis also about 5.0%-6.0%
the morphology and struture of the samples were characterized by scanning electron microscopy (SEM.) transmission electron microscopy and XRD. The residual carbon content of the resultant Li Hybrid materails was determined by carbon sulfur analyzer
