摘要：

In summary, a laser ablation method was used to prepare porous silicon-based nanoparticles with unique nanodandelion structures for anode materials of lithium-ion battery. The prepared nanodandelions showed a large capacity and stable the cycling performance. The improvement is mainly attributed to the porous nanostructure, which can tolerant the strains associated with the large volume expansion of siliconbased materials to avoid rapid capacity fading. In addition, the laser ablation method is simple, effective and can be scalable in preparing a large amount of porous silicon-based nanoparticles. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
