Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Hierarchical carbon electrodes</bold> with highly aligned carbon nanotube (CNT) fibrils are fabricated, and it is demonstrated that these electrodes, with aligned pores, can significantly enhance the cyclability and rate capability of Li−O₂ batteries. The highly aligned pore structure enables good accessibility of oxygen to the inner electrode, which leads to a uniform deposition of discharge products on the individual CNTs. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v8t2t97" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
