Alkaline Quinone Flow Battery with Long Lifetime at pH 12

(Joule 2, 1894–1906; September 19, 2018) In the originally published version of this article, the first panel of Figure 1 showing the DBEAQ synthetic route was omitted. It has now been included and appears below. Additionally, one of the reagents used in DBEAQ synthesis was described as “4-bromobutyrate” instead of the correct “methyl 4-bromobutyrate.” This has also now been corrected. The authors regret these errors.Figure 1.

It appears to be the first aqueous-soluble organic RFB chemistry to meet all the technical criteria for commercialization. The potential low reactant and membrane costs of this chemistry offer the potential for RFBs of this type to be used cost effectively at the gigawatt scale in order to enable massive penetration of intermittent renewable electricity.
