PNAS上一篇關(guān)于鋰電負(fù)極的文章 已有3人參與

PNAS上最近發(fā)表了一篇利用稻殼制備鋰電負(fù)極硅的文章,感覺(jué)很有趣,韓國(guó)人做的,拿出來(lái)和大家分享 貼出abstract: The rice husk is the outer covering of a rice kernel and protects the inner ingredients from external attack by insects and bacteria. To perform this function while ventilating air and moisture, rice plants have developed unique nanoporous silica layers in their husks through years of natural evolution. Despite the massive amount of annual production near 108 tons worldwide, so far rice husks have been recycled only for low-value agricultural items. In an effort to recycle rice husks for high-value applications, we convert the silica to silicon and use it for high-capacity lithium battery anodes. Taking advantage of the interconnected nanoporous structure naturally existing in rice husks, the converted silicon exhibits excellent electrochemical performance as a lithium battery anode, suggesting that rice husks can be a massive resource for use in high-capacity lithium battery negative electrodes.[ 來(lái)自小組 鋰電池世界 ] |
