Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Viswanathan, Venkatasubramanian -- Pande, Vikram -- Abraham, K M -- Luntz, Alan C -- McCloskey, Bryan D -- Addison, Dan -- New York, N.Y. -- Science. 2016 May 6;352(6286):667. doi: 10.1126/science.aad8689.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Mechanical Engineering, Carnegie Mellon University, Pittsburgh, PA 15213, USA. venkvis@cmu.edu. ; Department of Mechanical Engineering, Carnegie Mellon University, Pittsburgh, PA 15213, USA. ; Department of Chemistry and Chemical Biology, Northeastern University, Boston, MA 02115, USA. ; SUNCAT, SLAC National Accelerator Laboratory, Menlo Park, CA 94025, USA. ; Department of Chemical and Biomolecular Engineering, University of California, Berkeley and Energy Storage and Distributed Resources Division, Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA. ; Liox Power Inc., 129 North Hill Avenue, Suite 103, Pasadena, CA 91106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/27151860" target="_blank"〉PubMed〈/a〉
