Cover Picture: Nanostructured Electrodes and the Low-Temperature Performance of Li-Ion Batteries (Adv. Mater. 1/2005)

Authors


Abstract

The cover image shows a scanning electron micrograph of a commercially available track-etch polycarbonate filter. This porous membrane serves as the host for the template-synthesis of V2O5 nanowires of various diameters. Nanowires that are 70 nm in diameter are shown in the inset. Because V2O5 reversibly intercalates Li-ions, it has potential for use as a cathode material in Li-ion batteries. On p. 125, Sides and Martin report the use of these V2O5 nanowires as tools to investigate the poor low-temperature performance of Li-ion batteries.
