Si/C composite was prepared by ball milling and subsequent pyrolysis process using nanosilicon, flake graphite, and phenolic resin as raw materials. The effect of different binders on the performance of Si/C composite was investigated. XRD and FT-IR were used to characterize the structure of the binders, and SEM was used to characterize the morphology of the electrodes. The electrochemical results...
The silicon/graphite/carbon (SGC) composite was successfully prepared by ball-milling combined with pyrolysis technology using nanosilicon, graphite, and phenolic resin as raw materials. The structure and morphology of the as-prepared materials are characterized by X–ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). Meanwhile, the electrochemical...
LiCrxMn2−xO4 (x = 0, 0.02, 0.05, 0.12) materials were effectively synthesized by imidazolium-based ionic liquid as reaction medium at ambient pressure. The morphologies of Cr-doped LiMn2O4 via calcination were characterized by scanning electron microscopy (SEM). SEM reveals that the LiCr0.12Mn1.88O4 sample has regular nanostructure and a uniform particle size of 50–100 nm. Among the four samples...
