Seminar: "Graphene for lithium batteries: a real wonder or just hype? An overview on the development of graphene-based materials for lithium-ion and lithium-sulfur batteries at the Helmholtz Institute Ulm (HIU)”
Speaker: Dr. Alberto Varzi
From: Helmholtz Institute Ulm (HIU), Germany
Since its first isolation in 2004, graphene has become one of the hottest topics in the field of materials science, and its highly appealing properties have led to a plethora of scientific papers. Among the many affected areas of materials science, this ‘graphene fever' has substantially influenced the world of electrochemical energy-storage devices and, in particular, batteries. However, although an impressive amount of data has been collected, a real advance in the field still seems to be missing.
This lecture will give an overview on the use of graphene both as bare active material and as component in hybrids, highlighting the pros and cons of the "wonder material". Particular attention will be given to lithium-ion and lithium sulfur batteries, and to the synthesis route to obtain graphene-based materials with electrochemical properties tuned ad-hoc for each specific application.
