From reed plants to high performance anodes
Anodes based on silicon promise a very high capacity for Li-batteries, yet a sufficiently fast kinetics has to rely on a suitable nanostructure that allows for nanoscopic ionic and electronic wiring. The contribution shows that such Si-anodes can be obtained right away from processing reed plants with their preformed nanostructure and the silicate constituents acting as Si-source. The so-prepared electrodes show excellent storage behavior.
