Preparation and Characterization of Three Dimensional Sn-Co Alloy Based on Porous Ni for Lithium-ion Batteries

摘要

A three-dimensional dendritic Sn-Co anode was prepared on the porous Ni substrate via pulse current electrodeposition methond, and characterized by means of scanning electron microscope (SEM), energy dispersive (EDX) analyzer. Then its electrochemical property were studied by means of charging-discharging (C-D) test. The influences of the current density and eletrochemical technique has been studied. Besides this, the importance of annealing for the cycling performance of the as-prepared electrode had been dicussed.
