Abstract/OtherAbstract:
Unravelling the fundamentals of Li-O2 battery chemistry is crucial to develop practical cells with energy densities that could approach their high theoretical values. We report here a straightforward chemical approach that probes the outcome of the superoxide O2-, thought to initiate the elec-trochemical processes in the cell. We show this serves as a good measure of electrolyte and binder stability. Superoxide readily dehydrofluorinates polyvinylidene to give byproducts that react with catalysts to produce LiOH. The Li2O2 product morphology is a function of these factors, and can affect Li-O2 cell performance. This methodology is widely applicable as a probe of other potential cell components.
