Caption: By precisely controlling the process used to make them, Stanford and SLAC researchers can produce pomegranate clusters of a specific size for silicon battery anodes.
Left: Microscopic clusters form a fine black powder that can be coated on foil to create an anode. Middle: A single cluster.
Right: In this close-up of a cluster, a silicon nanoparticle can be seen inside its yolk shell, with space to swell during battery charging.
