Totally tubular electrodes: A new design is proposed for nanostructured electrodes for high-performance lithium batteries (see picture) based on the use of carbon tube-in-tube (CTIT) as both a nanoreactor and an efficient ion- and electron-conducting network. A V2O5/CTIT nanocomposite electrode is prepared to demonstrate this concept. The resulting materials exhibit a significant improved lithium-storage performance.
