Facile synthesis of hollow Cu(2)Sb@C core-shell nanoparticles as a superior anode material for lithium ion batteries

Abstract

Nanostructured Cu(2)Sb@C material was prepared through a simple polyol approach. Hollow Cu(2)Sb@C core-shell nanoparticles were obtained by controlling the amount of CuCl(2) and time of replacement reaction. The hollow Cu(2)Sb@C nanoparticle electrode showed excellent cycling performance.
