A Novel 3D porous Sn-Cu architecture was prepared as an anode material for use in an advanced lithium-ion battery. Micro-lamellar-structured 3D porous copper (Cu), which was electroless-plated with tin (Sn) as an active material, was used as anode current collector. Additionally, the micro-lamellar-structured 3D porous Sn-Cu anode was heat-treated to improve the bonding between the Cu and Sn and hence, the cyclability of the lithium-ion battery. The microstructure and composition of the 3D porous Sn-Cu anode was characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and electron dispersive X-ray spectroscopy (EDX). Furthermore, its electrochemical properties were investigated by cyclic voltammograms and galvanostatic charge/discharge voltage profiles. Electrochemical tests exhibited that the 3D porous Sn-Cu anode showed superior capacity and coulombic efficiency compared to the baseline Sn-coated Cu foil anode.
