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

ScienceNOW - Fetched: May 5th, 2016, 4:00pm UTC

We described a lithium-oxygen (Li-O2) battery comprising a graphene electrode, a dimethoxyethane-based electrolyte, and H2O and lithium iodide (LiI) additives, lithium hydroxide (LiOH) being the predominant discharge product. We demonstrate, in contrast to the work of Shen et al., that the chemical reactivity between LiOH and the triiodide ion (I3–) to form IO3– indicates that LiOH can be removed on charging; the electrodes do not clog, even after multiple cycles, confirming that solid products are reversibly removed.
