Preparation and characterization of binary and ternary tin-based alloy powders for lithium ion battery

Binary and ternary Sn-based alloy powders were successfully prepared by chemical reduction method. The physical properties of the alloy powders were determined by X-ray diffraction, field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), and nitrogen adsorpti...
