摘要
This review outlines the developments and recent progress in metal-assisted chemical etching of silicon, summarizing a variety of fundamental and innovative processes and etching methods that form a wide range of nanoscale silicon structures. The use of silicon as an anode for Li-ion batteries is also reviewed, where factors such as film thickness, doping, alloying, and their response to reversible lithiation processes are summarized and discussed with respect to battery cell performance. Recent advances in improving the performance of silicon-based anodes in Li-ion batteries are also discussed. The use of a variety of nanostructured silicon structures formed by many different methods as Li-ion battery anodes is outlined, focusing in particular on the influence of mass loading, core-shell structure, conductive additives, and other parameters. The influence of porosity, dopant type, and doping level on the electrochemical response and cell performance of the silicon anodes are detailed based on recent findings. Perspectives on the future of silicon and related materials, and their compositional and structural modifications for energy storage via several electrochemical mechanisms, are also provided.
这评论在硅的帮助金属的化学蚀刻构画出开发和最近的进步,总结许多基本、创新的过程并且蚀刻形成大量 nanoscale 硅结构的方法。,为 Li 离子电池的阳极也是的硅的使用考察了因素象电影厚度那样,做, alloying,和他们对可逆 lithiation 进程的反应关于电池房间性能被总结并且讨论。在在 Li 离子电池改进基于硅的阳极的表演的最近的进展也被讨论。当 Li 离子电池阳极被构画出,许多 nanostructured 硅结构的使用由许多不同方法形成了,特别地集中于集体装载,核心壳结构,传导性的添加剂,和另外的参数的影响。电气化学的反应和硅阳极的房间性能上的孔,掺杂物类型,和做的水平的影响基于最近的调查结果被详细说明。硅和相关材料的未来上的观点,和他们为经由几电气化学的机制的精力存储的组合、结构的修正,也被提供。
