Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201570002-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>High concentrations of electroactive materials are essential to achieve high energy densities in redox flow batteries. In article number 1400678, Wu Xu, Wei Wang, and co‐workers describe a molecular engineering strategy that introduces a polar ionic group to the ferrocene, leading to a 20‐fold increase in its solubility and thus energy density. When tested in a non‐aqueous Li‐organic flow cell with a Li‐graphite hybrid anode, the redox electrolyte produces an energy density of 50 Wh L⁻¹ and an energy efficiency &gt;75% with decent cyclability. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh30vdmd1h" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
