Metallic aluminum nanorods: Synthesis via vapor-deposition and applications in al/air batteries

The fabrication of Al nanorods by a facile vapor-deposition method and their electrochemical performance in Al/air batteries was reported. Aluminum electrodes were prepared by inserting the mixture of active materials Vulcan XC-72 carbon, and poly(tetrafluoroethylene). Al nanoparticles and nanowires have been synthesized by various methods, such as electromigration, electron-beam direct writing lithography, and template processing. Aluminum nanorods were prepared by loading Al powders of 99.99% purity in tungsten boats positioned at middle of a horizontal ceramic tube that was mounted in the center of a conventional tube furnace. The structure developed underwent powder X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. Al/air battery as prepared from Al nanorods displays high discharge specific capacity and average operating voltage, for developing long life battery systems.
