Abstract

Copyright 2016 by the American Association for the Advancement of Science; all rights reserved. Liu et al. (Research Article, 30 October 2015, p. 530) described a lithium-oxygen (Li-O2) battery based on lithium iodide (LiI)-assisted lithium hydroxide (LiOH) formation and decomposition.We argue that LiOH cannot be oxidized by triiodide (I3 -). The charge capacity is from the oxidation of I- instead of LiOH. The limited-capacity cycling test is misleading when the electrolyte contributes considerable parasitic reaction capacity.
