Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201304736-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Electrochemical deposition of MnO₂ onto carbon nanotube (CNT) yarn</bold> gives a high‐performance, flexible yarn supercapacitor. The hybrid yarn's blended structure, resulting from trapping of MnO₂ in its internal pores, effectively enlarges electrochemical area and reduces charge diffusion length. Accordingly, the yarn supercapacitor exhibits high values of capacitance, energy density, and average power density. Applications in wearable electronics can be envisaged. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg52wtn32t" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
