Abstract
A 3D mechanical stable scaffold is shown to accommodate the volume change of a high specific capacity nickel-tin nanocomposite Li-ion battery anode. When the nickel-tin anode is formed on an electrochemically inactive conductive scaffold with an engineered free volume and controlled characteristic dimensions, it exhibits significantly improved the cyclability.
