Silicon nanowires-carbon composite as anode material

Published on 12 March 2020
Nanostructured Silicon based materials enhance strongly the energy density, but electrode swelling in cycling induces fast capacity fading. Making Si-rich electrodes with high enough loading (high Silicon content, and high electrode density and thickness) remains a challenge.

We develop composite materials based on the growth of Silicon nanowires directly on graphite micron-sized flakes. The silicon nanocomponent gives a high lithium storage capacity to the composite, while the graphite microcomponent brings stability.
