Abstract

Abstract. A study of the performance of metallurgical grade silicon as active material of electrodes of lithium ion batteries has been performed. The study has been carried out by means of charge and discharge galvanostatic measurements comparing between samples with different contents of impurities. This allows to elucidate the effect of the presence of certain impurities in the performance of the material in batteries. Unlike other existing works, this one has the particularity of showing specifically the concentration and type of impurities in the active material. Resumen. Se ha realizado un estudio del rendimiento de silicio de grado metalúrgico como material activo de electrodos de baterías de ión litio. El estudio se ha basado en mediciones de carga y descarga galvanostática, comparando entre muestras con diferente contenido de impurezas. Esto permite dilucidar el efecto de la presencia de ciertas impurezas en el rendimiento del material en baterías. A diferencia de otros trabajos existentes, este tiene la particularidad de mostrar específicamente la concentración y tipo de impurezas en el material activo.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
