Abstract

A 3D mechanically stable scaffold is shown to accommodate the volume change of a high-specific-capacity nickel-tin nanocomposite during operation as a Li-ion battery anode. The nickel-tin anode is supported by an electrochemically inactive conductive scaffold with an engineered free volume and controlled characteristic dimensions, which engender the electrode with significantly improved cyclability.
