説明
Energy storage by organic redox-active molecules is based on the electromotive force produced from a couple of molecules which are different in redox potentials. Reversible and high-density charge storage by redox polymers ( [Red/Ox]polym ) require charge transport and electroneutralization by electrolyte ions throughout the polymer layer populated in high density with the redox-active groups. Charging/discharging capabilities are accomplished by fabricating organic rechargeable air batteries ((-) M | [Red]polym ↔ [Ox]polym | KOH, H2O | C (catalyst), O2 (+)), using polymer layers as the anode-active material which undergo reversible charging at potentials more negative than that of O2. Nonconjugated polymers with various types of main chains populated with anthraquinone derivatives per repeating unit have been synthesized with a view to unravel their charge transport and storage properties based on the n-type redox reactions. Anthraquinone-functionalized polymers have been proposed as a new class of anodeactive materials with negative charge storage properties and large redox capacities, as a result of the capability of using almost all of the redox sites in the polymer. The polymer/carbon composite layer allowed efficient swelling of the polymer in aqueous electrolyte solutions, giving rise to the rechargeable air battery effect with more than 500 charge/discharge cycle performances.
