Correction to Conversion Reaction of Nanoporous ZnO for Stable Electrochemical Cycling of Binderless Si Microparticle Composite Anode

Redox cycling in nanoporous electrochemical devices.

Nanoscale redox cycling is a powerful technique for detecting electrochemically active molecules, based on fast repetitive oxidation and reduction reactions. An ideal implementation of redox cycling sensors can be realized by nanoporous dual-electrode systems in easily accessible and scalable geometries. Here, we introduce a multi-electrode array device with highly efficient nanoporous redox cy...

In-situ TEM Observation of Electrochemical Cycling of a Si/TiO2 Composite NW

Graphite has been the most widely used Li-ion battery anode material due to its low lithiation potential and high capacity [1]. However, commercial use of graphite poses the potential problem of catastrophic battery failure due to short-circuiting via lithium electroplating. Hence, new state-of-the-art systems for anodes are unde r i nvestigation, a nd silicon, in particular, has attracted grea...

Characterization of Nanocrystalline Si-MCMB Composite Anode Materials

High rate and stable cycling of lithium metal anode

Lithium metal is an ideal battery anode. However, dendrite growth and limited Coulombic efficiency during cycling have prevented its practical application in rechargeable batteries. Herein, we report that the use of highly concentrated electrolytes composed of ether solvents and the lithium bis(fluorosulfonyl)imide salt enables the high-rate cycling of a lithium metal anode at high Coulombic ef...

Synthesis of Si-Sb-ZnO Composites as High-Performance Anodes for Lithium-ion Batteries

The Si-Sb-ZnO composites were prepared by a chemical reduction-mechanical alloying method and were employed as anode materials for lithium-ion batteries. The electrochemical performance of the Si-Sb alloy was significantly improved by the addition of ZnO nanoparticles. Especially, the initial specific charge and discharge capacities for Si-Sb-(ZnO)0.3 composite were 845.1 and 1301.5 mAh/g, resp...
