Abstract: The present invention relates to redox flow batteries (RFBs) which are tolerant to dioxygen, a method of preparing a RFB in the presence of dioxygen, and a method of charging and/or discharging a RFB and its use in the presence of dioxygen. The RFB comprises an electrolyte, the electrolyte comprising an organic redox-active molecule comprising a redox-active unit with two or more heteroarylene groups wherein the two or more heteroarylene groups are conjugated within the redox-active unit and at least a portion of the redox-active units are present as a complex formed of a singly reduced form of the redox-active unit, and wherein molecular dioxygen (O2) dissolved in the electrolyte. The RFB of the invention can be operated in the presence of dioxygen, removing the need for the creation of strict dioxygen-free conditions by purging, sealing and flowing inert gas through the RFB.

Abstract: A process of making an adsorbent body, wherein the process includes the steps of: (a) contacting adsorbent material with an initial mixture to form a solvated adsorbent mixture in a first solvent; (b) removing the first solvent and removing at least some of the first solvent from the solvated adsorbent mixture in the first solvent to form an initial adsorbent body; (c) contacting the initial adsorbent body with a second solvent to form a reduced-binder adsorbent body in a second solvent; and (d) solvent-drying the reduced-binder adsorbent body to form the adsorbent body. Also described is an adsorbent body, and the use of the adsorbent body in gas storage.
