Abstract:
Cu3Si@Si core-shell nanoparticles with a Si shell coated over the Cu3Si core are synthesized by a solid-state reaction between CuCl and Si. The evaluation process of the core-shell structure shows a mechanism analogous to the Kirkendall effect. As anode materials for lithium ion batteries, Cu3Si@Si core-shell nanoparticles retained a capacity of 903.6 mA h g(-1) at the current density of 2 A g(-1) over 400 cycles.
