  1. Iron Nanoelectrodes for Powerful Air Batteries Daniel C. Ralph, Cornell University, ECCS 0335765 The objective of this project is to develop iron electrodes for metal-air batteries that charge and discharge more quickly than conventional metal-air batteries (i.e., have greater power densities). We deposit iron oxides as continuous nanoparticle coatings onto porous carbon nanomaterials, and use SEM-EDS mapping to visualize the degree that FeOx coats the pore walls of the carbon scaffold. The resulting electrodes are electrochemically reduced into metallic iron, and their normalized discharge capacity is compared to that of planar iron electrodes as current densities are increased.
