Metal-Air Batteries

Metal-Air Batteries

Research Project
Project Goals

Metal-O2 batteries operate via the electrochemical reaction of metal ions and oxygen to form metal oxide upon discharge and the reverse during charge.  This primary product formed on the electrocatalyst also happens to be a wide band-gap semiconductor /insulator.  This fact has direct ramifications for discharge, charge, and battery design.  In this work we want to show that the chemical composition, electrocatalyst surface structure, rate of electrochemical discharge, and depth of that discharge effect the morphology, shape and type of product.  We will show the different "types" of metal oxides through multi-scan cyclic voltametry in combination with in-situ electrochemical atomic force and scanning tunneling microscopy.  We hope to use this information along with properties of the electrocatalyst to engineer a more conductive solid product.
