Preparation of Tin Nano-Spheres Film Anode Based on Copper-Nickel Nano-Pillars for Lithium Ion Batteries

Abstract

Tin nano-spheres film was synthesized by electrodeposition based on the copper-nickel nano-pillars which were prepared by electrochemical method on the copper foil in an aqueous solution containing Cu (II) and Ni (II) at room temperature. The morphology, structure and composition of the as-prepared copper-nickel nano-pillars and tin nano-spheres were characterized by SEM, XRD, and EDS. The tin nano-spheres film anode features the large surface area, good electronic conductivity, and adhesion with the current collector, leading to the enhanced performance in lithium-ion batteries.

Nickel Nanopillar Arrays Electrodeposited on Silicon Substrates Using Porous Alumina Templates

“…For instance, Ni-Npillars have been used to develop potential lithium-ion battery electrodes [ 8 , 23 ]. Sn nanospheres were directly grown on Ni-Npillars to improve the volume charge in a lithium-ion battery anode; this alloy stabilizes the structure and suppresses the expansion during the reaction [ 24 ].…”
