Self-healing chemistry enables the stable operation of silicon microparticle anodes for high-energy lithium-ion batteries
Nature Chemistry. doi:10.1038/nchem.1802
Authors: Chao Wang, Hui Wu, Zheng Chen, Matthew T. McDowell, Yi Cui & Zhenan Bao
The ability to self-heal is an important survival feature in nature, with in-built systems working to correct faults and extend the lifetimes of organisms. Now, self-healing chemistry has been applied to overcome the short cycling lifetime of high-capacity rechargeable lithium-ion batteries with silicon-microparticle anodes that suffer from mechanical fractures.

Networks of silicon nanowires: A large-scale atomistic electronic structure analysis
Networks of silicon nanowires possess intriguing electronic properties surpassing the predictions based on quantum confinement of individual nanowires. Employing large-scale atomistic pseudopotential computations, as yet unexplored branched nanostructures are investigated in the subsystem level as well as in full assembly. The end product is a simple but versatile expression for the bandgap and band edge alignments of multiply-crossing Si nanowires for various diameters, number of crossings, and wire orientations. Further progress along this line can potentially topple the bottom-up approach for Si nanowire networks to a top-down design by starting with functionality and leading to an enabling structure.
