Catalyst‐free Direct Growth of a Single to a Few Layers of Graphene on a Germanium Nanowire for the Anode Material of a Lithium Battery1. Issue 23 (24th April 2013) - Kim, Hyungki
Abstract Direct growth 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 %.
