- Abstract
- This study investigates bundle-type silicon nanorods (BSNR) that are aimed at improving the discharge capacity and life cycle characteristics of secondary cells, by controlling the shape and etching depth of silicon thick-films produced by electroless etching. The prepared BSNR structure is composed of a columnar bundle, having a diameter of 100 nm and lengths of 1.5 and 3.5 mu m. The etching depths of the nanorods have a significant effect on the electrochemical performance characteristics, including the capacity fading and coulombic efficiency. Using a BSNR electrode therefore allows for an anode with a high capacity and efficiency in lithium ion cells, and can help overcome the issues associated with conventional silicon thick-films. Furthermore, as a result of its unique self-relaxant structure, electrode deterioration is improved through mitigation of the volume change. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
