[资源] PNAS最新文章—韩国科研人员用废弃稻壳制造锂电池

网易科技讯 7月13日消息，据国外媒体报道，韩国的一组研究人员在研究充分利用废弃稻壳，将它转化成硅，然后用于制造智能手机和混合动力汽车所需要的锂离子电池。文章摘要如下：
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.
