N-doped graphene/SnS composite as high-performance anode materials has been synthesized by a simultaneous solvothermal method using ethylene glycol as solvent. The morphology, structure, and electrochemical performance of N-doped graphene/SnS composite were investigated by transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectra, Fourier transform infrared (FTIR) spectra, X-ray...
Reduced graphene oxide/porous Si composite was fabricated through magnesiothermic reduction of mesoporous silica and subsequent dispersing porous Si in the suspension of graphene oxide followed by reduced process. The electrochemical performance of the obtained reduced graphene oxide/porous Si composite was investigated as anode for lithium ion batteries, and it delivers a reversible capacity...
Double-walled core-shell structured Si@SiO2@C nanocomposite has been prepared by calcination of silicon nanoparticles in air and subsequent carbon coating. The obtained Si@SiO2@C nanocomposite demonstrates a reversible specific capacity of about 786 mAh g−1 after 100 cycles at a current density of 100 mA g−1 with a capacity fading of 0.13 % per cycle. The enhanced electrochemical performance can be...
