Abstract

We report herein that the particle size of Li2O2, which is the discharged product of a Li–O2 battery, remarkably influences the charging performance. As the particle size decreases, the average voltage of charge plateaus is lowered due to reduced electrode polarization and enhanced kinetics of the oxidation reaction of Li2O2.
