Facile synthesis of hollow Cu2Sb@C core-shell nanoparticles as a superior anode material for lithium ion batteries

摘要

Nanostructured Cu2Sb @C material was prepared through a simple polyol approach. Hollow Cu2Sb@C core-shell nanoparticles were obtained by controlling the amount of CuCl2 and time of replacement reaction. The hollow Cu2Sb@C nanoparticle electrode showed excellent cycling performance.
