High‐Rate, Long‐Life Ni–Sn Nanostructured Electrodes for Lithium‐Ion Batteries

Abstract

In this paper, we report a revolutionary, new type of nanoarchitectured configuration that results in electrodes that have very high rate capability and excellent capacity retention. The new electrode configuration designed in this work was prepared by a template synthesis procedure that initially involved the formation of a nanoarchitectured Cu current collector. This was obtained by growing a 3D array of Cu nanorods onto a Cu foil by electrodeposition through a porous alumina membrane that was subsequently dissolved
