AbstractTwo-dimensional (2D) elemental metals, often overlooked owing to their lack of switching or dielectric properties, have the potential to exhibit unique properties unachievable by their bulk counterparts if their microstructure can be controlled. Here we propose an electrodeposition method that utilizes a confined 2D template to prepare elemental metal nanosheets with an aligned grain orientation, resulting in an exceptionally high in-plane electrical anisotropy of >103.

1 Introduction Clean energy storage technologies are critical to transform the fossil fuel-based transportation sector and to store energy from intermittent renewable sources. Supercapacitors have gained much attention due to their fast charging and discharging times, and their long cycle lifetimes.[1] These electrochemical devices usually consist of two solid electrodes, an ion-permeable separator, and a liquid electrolyte.
