Lithium‐Ion Batteries: Nanostructured Fe₃O₄/SWNT Electrode: Binder‐Free and High‐Rate Li‐Ion Anode (Adv. Mater. 20/2010)

A flexible carbon nanotube net is employed to demonstrate high capacity/high volume expansion materials for Li-ion battery electrodes, as presented by A. C. Dillon et al. on page E145. An electrode, with well over twice the capacity of the state-of-the-art technology, charges and discharges in 12 minutes without significant capacity fade. These advancements, funded by the US Department of Energy, Office of Vehicle Technologies Program, will help enable next generation electric vehicles.
