Si-based anode materials provide a promising way to improve the energy density of lithium-ion batteries (LIBs) due to its environmentally friendly character,natural abundance,理论容量高，工作电压吸引人。However,huge volume variation during lithiation/delithiation and low electric conductivity of Si make it challenging for practical applications of Si-based materials.Yu-Guo Guo and coworkers at Institute of 新利手机客户端Chemistry,中国科学院分析了硅基阳极的锂硅合金化和新利手机客户端电池失效机理，总结了硅基阳极材料的研究进展。为了获得高可逆容量和良好的循环稳定性，nano/micro-structured Si/C and SiO_X/讨论了具有三维导电网络和稳定界面的复合阳极。The researchers proposed the key aspects of Si-based materials and prospective strategies for promoting the practical applications of Si-based anodes in high energy density Li-ion batteries.

三元氯化银纳米晶体：尺寸和形貌对光催化活性的内在影响

萨西塔C.Abeyweera and Yugang Sun*
DOI: 10.1039/C7QM00046D,研究文章
First published online on 09 Mar 2017

编辑意见：

Stirring rate plays a significant role in determining the mass diffusion and thus nucleation and growth kinetics of forming colloidal nanocrystals in particular in high-viscosity solutions even though its importance is usually overlooked.  By controlling the rate of solution stirring,Abeyweera and Sun from Temple University demonstrated the successful synthesis of various silver chlorobromide (AgCl_XBr_1-x）通过乙二醇中银离子和卤化物离子的沉淀反应来控制尺寸和形态的纳米颗粒。合成的AgCl_XBr_{1 x}纳米颗粒提供了一个独特的平台来精确研究其光催化活性对粒径（决定电荷分离效率）和形态（决定催化表面类型）的依赖性。
