<P>Unraveling the fundamentals of Li-O<SUB>2</SUB> batterychemistryis crucial to develop practical cells with energy densities that couldapproach their high theoretical values. We report here a straightforwardchemical approach that probes the outcome of the superoxide O<SUB>2</SUB><SUP>–</SUP>, thought to initiate the electrochemicalprocesses in the cell. We show that this serves as a good measureof electrolyte and binder stability. Superoxide readily dehydrofluorinatespolyvinylidene to give byproducts that react with catalysts to produceLiOH. The Li<SUB>2</SUB>O<SUB>2</SUB> product morphology is a functionof these factors and can affect Li-O<SUB>2</SUB> cell performance.This methodology is widely applicable as a probe of other potentialcell components.</P><P><B>Graphic Abstract</B>
