Multiple directions in battery research are now being pursued with the goal of advancing beyond the specific energy limits imposed by conventional Li-ion battery electrode materials. For example, ‘beyond Li-ion’ battery chemistries, such as alkali metal-O2, Li-S, and Mg-ion, are currently being explored given their very high theoretical specific energies. Nevertheless, severe technical challenges have prohibited these potential battery chemistries from supporting practical systems. The objective of this presentation is to provide an update of recent results from our laboratory on challenges facing the electrochemistry in nonaqueous metal-air (O2) batteries. Results will be presented on product formation and oxidation processes in Li and Na-O2 batteries and how these processes ultimately affect battery performance.
