Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Direct growth</bold> of a single to a few layers of graphene on a germanium nanowire (Gr/Ge NW; see picture) was achieved by a metal‐catalyst‐free chemical vapor deposition (CVD) process. The Gr/Ge NW was used as anode in a lithium ion battery. This material has a specific capacity of 1059 mA h g⁻¹ at 4.0 C, a long cycle life over 200 cycles, and a high capacity retention of 90 %.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg21fg3fjq" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
