Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Cyclized‐polyacrylonitrile (cyclized‐PAN) is used as a conformal coating on nano‐Si for highly reversible anodes.</bold> Cyclization of PAN proceeds by limiting the pyrolysis to 300 °C such that the cyclized‐PAN maintains its polymeric properties while also providing sp² π bonding for good electronic conductivity. Cyclized‐PAN is thus a conjugated polymer with good mechanical resiliency to accommodate Si's volumetric expansion and also good mixed conductivity. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg21ffmkvj" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
