Abstract

3D nanoporous Au-supported nano­crystalline tin thin-film anodes for Li-ion batteries are prepared by dealloying followed by electroless plating. When used as an electrode for Li-ion batteries, this special Sn structure can effectively accommodate large volume variations during cycling in a lithium cell, resulting in improved capacity retention.
