When manufacturers slice high-purity silicon ingots to produce wafers for electronics, they can lose almost half of the material to a sludgy waste. Now, researchers have developed a method to reclaim silicon nanoparticles from that sludge and have incorporated the Si into the anodes of lithium-ion batteries (Sci. Rep. 2015, DOI: 10.1038/srep09431). Led by Jiaxing Huang of Northwestern . . .
