Ionic-Liquid-Nanoparticle Hybrid Electrolytes: Applications in Lithium Metal Batteries.

by Angewandte Chemie
Authors: Lu Y, Korf K, Kambe Y, Tu Z, Archer LA Abstract Development of rechargeable lithium metal battery (LMB) remains a challenge because of uneven lithium deposition during repeated cycles of charge and discharge. Ionic liquids have received intensive scientific interest as electrolytes because of their exceptional thermal and electrochemical stabilities. Ionic liquid and ionic-liquid-nanoparticle hybrid electrolytes based on 1-methy-3-propylimidazolium (IM) and 1-methy-3-propylpiperidinium (PP) have been synthesized and their ionic conductivity, electrochemical stability, mechanical properties, and ability to promote stable Li electrodeposition investigated. PP-based electrolytes were found to be more conductive and substantially more efficient in suppressing dendrite formatio...

Self-healing chemistry enables the stable operation of silicon microparticle anodes for high-energy lithium-ion batteries

by Chao Wang

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.
