Abstract

original image

This false-colored SEM image shows a model high-energy- density lithium-ion battery anode that consists of an array of 3D hierarchically patterned single-crystalline silicon microstructures. Ralph G. Nuzzo and co-workers utilize these model anodes to demonstrate the crystallographic anisotropy of strain evolution on electrochemical intercalation of lithium atoms and self-strain-limited charging of a lithium-ion battery anode.
