[Technical Comment] Comment on “Cycling Li-O2 batteries via LiOH formation and decomposition”

Thursday, May 5, 2016 - 14:01 in Physics & Chemistry

Based on a simple thermodynamic analysis, we show that iodide-mediated electrochemical decomposition of lithium hydroxide (LiOH) likely occurs through a different mechanism than that proposed by Liu et al. (Research Article, 30 October 2015, p. 530). The mismatch in thermodynamic potentials for iodide/triiodide (I−/I3−) redox and O2 evolution from LiOH implies a different active iodine/oxygen electrochemistry on battery charge. It is therefore possible that the system described in Liu et al. may not form the basis for a rechargeable lithium-oxygen (Li-O2) battery. Authors: Venkatasubramanian Viswanathan, Vikram Pande, K. M.
