Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401946-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A honeycomb layered Na₃Ni₂SbO₆</bold> is synthesized as a cathode for sodium‐ion batteries. This new host material exhibits a high capacity of 117 mA h g⁻¹, a remarkable cyclability with 70% capacity retention over 500 cycles at a 2C rate, and a superior rate capability with &gt;75% capacity delivered even at a very high rate of 30 C (6000 mA g⁻¹). These results open a new perspective to develop high‐capacity and high‐rate Na‐ion batteries for widespread electric‐energy‐storage applications. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1f8bcthc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
