摘要

A three-dimensional cellular silicon-based anode was prepared by casting milled silicon powders into the "valley-ridge" copper architecture, then its electrochemical property and failure mechanism were studied by means of charging-discharging (C-D) test, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). In comparison with common 2D anode fabricated by "slurry-coating" technology on flat copper foil, the 3D copper framework has shown a great structure advantage in restricting severe volume changes of silicon particles. This "stress-alleviated" action can effectively impede strain-induced loosening happened inside electrodes during charging and discharging, and consequently improve cycle-life and coulombic efficiency of silicon-based anode.
