Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgjbfb1qm1" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />A redox-active and water-insoluble polyimide can reversibly bind 2 Na⁺ ions per molecular unit, demonstrating a high capacity of 130 mA h g⁻¹, a strong rate capability at 10 C rate and excellent capacity retention of 91.2% over 1000 cycles, offering a low cost and environmentally benign anode for aqueous Na-ion batteries.</p> </abstract>
