Composites Based on Intermetallic Nanoparticles for a New Generation of Electrochemical Systems

Abstract:

Intermetallic (Ni-Sn) nanoparticles are synthesized through a borohydride reduction with NaBH₄ in a mixture of aqueous solutions of NiCl₂.6H₂O and SnCl₂.2H₂O at mass ratio and Ni:Sn = 45:55. The ratio is chosen in accordance with the Ni-Sn binary system phase diagram. A "template" technique which involves borohydride reduction of intermetallic nanoparticles on a support (carbon foam, graphite, carbon powder) is also used. The samples which are Ni-Sn alloys and carbon-based nanocomposites are studied by scanning electron microscopy (SEM), and X-ray diffraction (XRD) analysis. The samples are electrochemically tested as electrode materials in Li-ion batteries.
