Nanocomb Architecture Design Using Germanium Selenide as High Performance Lithium Storage Material

 

Hyungki Kim, Yeonguk Son, Jinho Lee, Minkyung Lee, Seungkyu Park, Jaephil Cho* and Hee Cheul Choi*

We synthesized a unique GeSe nanocomb architecture with well-devoloped teeth on a backbone using a simple vapor-solid (VS) method. This GeSe nanocomb architecture exhibited great synergy with intrinsic structural advantages of GeSe material as a basic unit of nanostructure. As a result the designing of nanocombs architecture gave structural robustness to the anode material, so that it could withstand tremendous volume expansion; they also facilitated lithiation/delithiation to guarantee high rate capability. GeSe nanocomb architecture accomplished the remarkable cycling performance with high capacity retention >89% after 1000 cycles at 1.0 C and exhibited high rate capability of 331 mAhg−1 at 20 C
