Abstract:The choice of SiO 2 precursor plays an important role in designing and synthesizing specific nanostructured Si materials with improved Li-storage performance. Herein, various SiO 2 precursors are used to prepare nanostructured Si spheres via zincothermic reduction and their effects on the reduction process are systematically investigated. It is found that the size and structure of SiO 2 precursors have a significant effect on the zincothermic reduction process. Among various precursors, nano-SiO 2 and bio-SiO … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
